Abstract
Lipomas are slow-growing, benign mesenchymal masses. Most lipomas are small, weighing only a few grams; however, if their size becomes exceptionally large, they are called giant lipomas. Giant lipoma of the breast is infrequently observed due to the rarity of size and location, with very few case reports available in the literature. Here, we report the case of a 48-year-old female patient who presented with a painless, huge lump in her right breast. The patient underwent surgical removal of the mass with a histologic examination confirming the diagnosis of a giant breast lipoma.

Abstract
To investigate the accuracy of computed tomography (CT) in evaluating spinal epidural adipose tissue compared to magnetic resonance imaging (MRI).CT scan images and matched magnetic resonance images of total 368 patients between July 2014 and July 2016 were evaluated. Hounsfield units (HU) of epidural fat (EF), dural sac (DuS), ligamentum flavum, bone of facet joints, and paraspinal muscles were measured for comparison. Anteroposterior diameter of the EF, anteroposterior diameter of the DuS, transverse diameter of the DuS, cross-sectional area of the EF, and cross-sectional area of the DuS were measured at each disc level from L1-2 to L5-S1.Fat tissue showed exclusive negative HU significantly different from all other periphery tissues. Pearson correlation coefficient analyses showed significant positive correlations between CT and MRI measurements; Bland-Altman plots also depicted satisfied agreement. Overgrowth of spinal EF was more commonly found at L2-3 and L3-4 levels in present study, and body weight, age, and gender were significantly associated with amounts of EF both on CT and MRI.The CT scan is a satisfied alternative of MRI for the evaluation of spinal epidural adipose tissue.

Abstract
A 9-year-old female rose-breasted cockatoo (Eolophus roseicapilla) was presented for a humeral fracture. At presentation, the bird was severely lethargic and obese. On physical examination, an open right humeral fracture, healed left ulnar fracture, and intertarsal joint swelling were present. Results of hematologic testing and biochemical analysis revealed severe leukocytosis with heterophilia and increased creatine kinase and aspartate aminotransferase activities consistent with musculoskeletal lesions. Radiographs confirmed a right humeral fracture and showed severe polyostotic lytic and expansile lesions of the appendicular skeleton, as well as an enlarged hepatic silhouette. Surgical repair of the fracture was attempted, but the bird died during the procedure. Postmortem examination revealed severe bone deformities involving the fractured humerus, both ulnas, and the left tibiotarsus. Histologic findings were consistent with multiple intraosseous lipomas of the long bones and severe hepatic lipidosis. To our knowledge, this is the first report of multiple intraosseous lipomas in a bird.

Abstract
BACKGROUND Intraosseous lipoma is a rare benign lesion, commonly affecting the os calcis. Its pathogenesis and natural history are not fully understood, and its management remains controversial.
CASE SUMMARY A 56-year-old male complaining of heel pain was diagnosed with an os calcis lipoma. The lesion was treated with curettage and it was filled with impacted allograft and demineralized bone matrix. Histological examination confirmed the above diagnosis. Six months postoperatively, the patient returned to recreational long-distance running. Repeated computed tomography scanning, up to five years postoperatively, showed almost complete resorption of the graft over time.
CONCLUSION The treatment of an os calcis lipoma should be individualized, depending on the symptoms, the location and size of the lesion. Surgeons, electing to proceed with bone grafting, should consider the probability of bone graft resorption.

Abstract
STUDY DESIGN Case report. OBJECTIVE This case report is unique since this is the first vertebral lipom case that was treated by kyphoplasty alone. SUMMARY OF BACKGROUND DATA Vertebral lipoma is extremely rare and our search of the English literature has revealed 20 patients in 16 reports. METHODS A 32-year-old female patient was admitted to our neurosurgery department with the chief complaint of low back pain that had lasted nearly 1 year. A lumbar MR suggested a hemangioma and the patient was operated on. RESULTS On microscopic examination, the lesion was seen to have a widely infiltrating appearance of mature fat tissue between bone trabeculae diagnosis was intraosseous lipoma. CONCLUSION We believe that the management should be surgical total removal of the lesion even in incidentally found cases in order to obtain histologic diagnosis and pain relief. LEVEL OF EVIDENCE 5.

Abstract
Large soft tissue tumors — 5 cm or greater — or deep-seated tumors have a greater risk of being malignant than smaller and superficially located tumors (9). In a period of 2 years 43 consecutive patients with lipomatous tumors 5 cm in diameter or greater were examined with MR imaging. The MR findings were correlated to histologic features and diagnosis. Twenty-six tumors were classic lipomas both on MR and at microscopy; 8 lipomas showed other features — some of them raising suspicion of malignancy at MR; all, however, were histologically benign. Nine tumors were considered malignant at MR imaging; all 9 proved to be malignant by microscopy.

Abstract
We report a case of a 22-year-old female who was operated at the age of 3 months for cervico-dorsal swelling. She presented with gradual onset, progressively worsening dull aching pain in the cervico-dorsal region, 21 years following previous surgery. Magnetic resonance imaging showed intradural dermoid cyst with the fluid level. She underwent excision of the dermoid cyst with excision of the wall. The clinical profile, etiopathogenesis, radiological features, and management of intraspinal dermoid cysts are discussed in the light of current literature.

Abstract
INTRODUCTION Intraosseous lipoma is a rare benign bone disease. Long and cancellous bones are the most locationsthat can be affected. Almost all lesions were discovered incidentally on imaging modalities that were done during an unrelated investigation. As it is rare, it may be mistaken for nonossifying fibroma, aneurismal bone cyst, simple bone cyst, bone infarct or chondroid tumors. Recently with the high quality imaging modalities such as CT scan and/or MR imaging, the diagnosis of intramedullary lipoma and some other bone lesions can be done without the need for bone biopsy and surgery. CASE REPORT We're reporting a rare case of intraosseous lipoma of the distal femur. Plain film radiography showed barely visible medullary expansion and lucency in the distal left femoral diaphysis. The patient underwent further evaluation with computed tomographic (CT) and magnetic resonance Imaging (MRI). According to the MRI and CT scan findings, intraosseous lipoma was confirmed and the need for more diagnostic tests were eliminated. CONCLUSION Although Intraosseous lipoma doesn't have any manifestations clinically but it should be considered in the differential diagnosis of bone pains. MRI has an important role in characterization of soft tissue and bone marrow lesions therefore non-surgical approach for most of the patients with intraosseous lipoma would be beneficial.

Abstract
Retropharyngeal lipomas are rare tumours that are usually asymptomatic until they reach a large size. The definitive treatment is surgical excision. Since the tumours are typically large at the time of presentation, extensive surgery for complete clearance of the lipoma from the retropharyngeal and parapharyngeal regions is to be expected. Transoral excision is typically indicated for small retropharyngeal tumours, as this approach does not give good access to the parapharyngeal area laterally. Herein, we present the case of a patient who underwent transoral excision of a huge retropharyngeal lipoma, which extended into the right parapharyngeal space. The surgical technique used and the insights gained are described in this report. Even with parapharyngeal extension, transoral resection of a huge retropharyngeal lipoma can be performed. More invasive surgery, which may involve a neck incision, mandibulotomy or pharyngotomy, is not necessary. While huge retropharyngeal lipomas are usually symptomatic and require surgical intervention, transoral resection can be adequate and safe for treatment.

Abstract
Lipomas are benign mesenchymal tumors that develop in areas of abundant adipose tissue. Due to the fatty composition of the breast, difficulties in diagnosis, treatment, and reconstruction are often encountered. We report a case of a 55-year-old female with a giant tumor of the right breast that comprised most of its mass, causing breast asymmetry. A thorough preoperative evaluation, followed by an uneventful difficult surgical resection and reconstruction, resulted in diagnosis of a benign lipoma. The case prompted this report because of its challenging size, location, diagnosis, and reconstructive solution.

Abstract
Intraosseous lipoma is a rare, benign primary tumor occurring in bone. In the present report, a case of an intraosseous lipoma of the calcaneus is presented, together with a focused review of published studies. Radiographically, the lesions will appear osteolytic and well delineated, displaying a central area of calcification. Curettage and packing with autogenous bone grafts was our treatment for this rare tumor. In the present case, and 1 previously published case, a central sclerotic mass was observed. The histologic findings were typical, with mature adipose tissue mixed with a few degenerated bone trabeculae.

Abstract
Introduction Hemangiopericytoma is an uncommon perivascular tumor. Rectal Hemangiopericytomas are extremely rare. To the best of our knowledge, only two cases have been reported in the literature. Case presentation We report the case of a 37-year-old Asian woman with an Hemangiopericytoma rising from the anterior wall of her rectum. Abdominopelvic computed tomography showed a 7.4 cm solid mass between her uterus and her rectum. Heterogeneous gradual enhancement after intravenous injection of contrast material was noted with several tortuous vessels around her tumor. Intra-operative findings indicated a capsule and well-circumscribed solid tumor connecting with the anterior wall of her rectum by a small pedicle. With immunohistochemical stains, her tumor cells reacted positive for Bcl-2, CD34, and ki67 and negative for CD10, CD117, S100, and Desmin. Follow-up computed tomography scans have shown no tumor recurrence or metastasis signs. Conclusions Rectal Hemangiopericytoma is a rare tumor with non-specific imaging findings. Hemangiopericytomas should be included in the differential list when a massive tumor with heterogeneously gradual enhancement in the regions of the rectum is encountered.

Abstract
Purpose/results. We evaluated the diagnostic accuracy of magnetic resonance imaging (MRI) for 46 consecutive patients
with lipomatous soft tissue tumors prior to biopsy and resection. Twenty-eight patients had benign lipomas and 18 had
liposarcomas. Clinical differences between thdse patients with benign disease and those with malignant lesions were
average age at the time of presentation (49 years for benign vs 62 years for malignant, p < 0.001) and average length of
symptoms prior to resection (64 months for benign versus 38 months for malignant, p = 0.01). MRI characteristics
associated with benign disease included: smaller tumor size (9.4 cm average greatest dimension for benign lesions vs
13.4 cm for malignant masses, p = 0.022); a mass with a uniformly homogeneous signal (p = 0.0003); a mass with
homogeneous high T1 and T2 signals and a low short-time-inversion-recovery (STIR) signal comparable to normal fat
(p < 0.0001). This last signal pattern was not seen in malignant lesions (0/18) and was present in almost all benign lipomas
(25/28). The usual MRI descriptions of soft tissue masses such as infiltrating vs encapsulating, deep vs subcutaneous and
septated vs non-septated were not helpful predictors of malignancy in this series. Needle biopsies of lipomatous masses
with heterogeneous signals on MRI resulted in inaccurate diagnoses due to sampling error in 5/9 patients. Discussion. A carefully planned and performed MRI study of lipomatous masses can accurately predict a benign lipoma
whenever a homogeneous high T1 and T2, as well as a low STIR, signal is present. However, a mass with any other signal
characteristics must be biopsied carefully in order to make an accurate diagnosis.

Abstract
Solitary fibrous tumour (SFT) is a rare soft tissue tumour of uncertain histogenesis and unpredictable biological behaviour, which was first described in the pleura and subsequently in many extra-pleural locations. Fat-forming SFT is a sub-type of SFT and only a handful of cases have been reported in the literature. We present the clinical, radiological and histological features of a case of intraspinal fat-forming SFT, along with a literature review. This is the first known report of a fat-forming SFT in the spine.

Abstract
We report a case with a primary giant cardiac lipoma in the right ventricle attached to the interventricular septum that involved the chordae of the septal leaflet of the tricuspid valve. As the potential for malignancy was low, tricuspid valve replacement and minimum tumor resection were performed to obtain a suitable route to the right ventricular outflow tract.

Abstract
Dedifferentiated liposarcoma was first described in 1979, and its definition has been recently extended. We found an undiagnosed anterior mediastinal mass in a 56- year-old man for whom we performed a complete tumor resection through median sternotomy. Microscopic examination revealed that the mass was primarily a low-grade, dedifferentiated liposarcoma, with a partial high-grade area. Occurrence of dedifferentiated liposarcoma in the anterior mediastinum is rare. We did not perform any adjuvant therapy. Three years after the surgery, the patient is alive without disease. In lipoma-like, well-differentiated liposarcoma cases, we should consider the possibility of dedifferentiated liposarcoma if a mild, atypical spindle cell component is found.

Abstract
BACKGROUND Lipoma-like liposarcomas mimic deep-seated lipomas in regard to imaging as well as histological findings and occasionally cause problems concerning diagnosis and treatment. The differences in the imaging findings among these lesions are not well defined. The purpose of this study was to elucidate the differences among the deep-seated adipocytic neoplasms including intramuscular lipoma, intermuscular lipoma, and lipoma-like liposarcoma. METHODS The imaging and clinicopathological findings of 40 intramuscular lipomas, 27 intermuscular lipomas, and 22 lipoma-like liposarcomas were evaluated, and the possibilities in the differential diagnosis were assessed. RESULTS Although the most frequent symptom was a palpable mass, swelling was a common symptom of intramuscular lipomas and lipoma-like liposarcomas. Imaging studies revealed dumbbell-shaped appearances among intermuscular lipomas, whereas spherical masses were characteristic of intramuscular lipomas and lipoma-like liposarcomas. Computed tomography and magnetic resonance imaging revealed fatty lesions containing streaky structures in benign lesions, and CT revealed foci of hazy amorphous density, representing spindle cell proliferation, in lipoma-like liposarcoma. Although streaky structures corresponding to entrapped muscle fibers were thick and occasionally interrupted in intramuscular lipomas, the streaky structures corresponding to areolar fibrous tissue were thin and were usually not interrupted in intermuscular lipomas. In lipoma-like well-differentiated liposarcomas, thick streaks represented entrapped muscle fibers, and thin streaks represented fibrous tissue or neoplastic spindle cell proliferation. CONCLUSIONS The imaging findings are helpful and often afford almost pathognomonic evidence of these lesions and could help with the selection of appropriate surgery.

Abstract
Lipomatous hypertrophy of the interatrial septum (LHIS) is a rare benign disorder that is characterized by accumulation and deposition of fat in the interatrial septum. Its etiology is still unknown, despite the theories that have been suggested. It usually occurs in older, obese people with a higher incidence in women. In most cases, it remains asymptomatic, thus its diagnosis is rarely made during a person's lifetime and it is made incidentally or during autopsy. LHIS can cause atrial arrhythmias, obstructive flow symptoms and sometimes death. The diagnosis of LHIS can be made by the use of imaging techniques, with the best results given by multislice-CT (MSCT) scanning. Surgical intervention is usually avoided and the best management is early diagnosis, reassurance and inactivity. However, in cases of severe superior vena cava obstruction or intractable rhythm disturbance, surgical excision is performed together with reconstruction of the interatrial septum.

Abstract
The differential diagnosis of extrahepatic abdominopelvic masses is wide. Demonstration of fat within a lesion at noninvasive imaging is an important clue for narrowing the differential diagnosis. Macroscopic fat is readily identified with both computed tomography (CT) and magnetic resonance (MR) imaging. Demonstration of microscopic fat is more difficult and may require special techniques. Identification of fat with CT is based on x-ray resorption and therefore on the attenuation (typically less than -20 HU). Several MR imaging techniques have been developed for fat suppression. Two of the most widely available are spectroscopic fat saturation and chemical shift (in-phase/opposed-phase) imaging. Entities with predominantly macroscopic fat include myelolipoma, angiomyolipoma, teratoma, liposarcoma, lipoma, epiploic appendagitis, omental infarction, and mesenteric panniculitis. Lesions with predominantly microscopic fat include adrenal adenoma and some teratomas. Other fat-containing entities involve the mesentery and bowel wall; these include fibrofatty mesenteric proliferation and submucosal fat deposition.

Abstract
Bronchial benign tumors comprise fewer than 4% of pulmonary neoplasms. Endobronchial lipoma is an extremely rare benign neoplasm accounting for only 0.1% to 0.5% of all lung tumors. Clinical symptoms of lipoma depend on the location of the tumor, the severity of bronchial obstruction, and the functional and anatomical effects on the parenchyma distal to the obstruction. Computed axial tomography usually reveals the adipose composition of the lipomatous tumor. We report the case of an 83-year-old man diagnosed with community-acquired pneumonia that led to complications: pleural empyema caused by Haemophilus influenzae infection and atelectasis of the right middle and lower lobes secondary to a lipomatous endobronchial obstruction. Removal of the bronchial lipoma was performed by laser resection.

Abstract
Intraosseous lipomas represent a small number of benign bone tumors with incidence rates of approximately 0.1%. In about 15% these neoplasias are localized within the calcaneus, mostly at Ward's triangle. The tumors usually remain clinically inapparent and diagnosis is often obtained incidentally. Although CT scan and MRI provide specific and sensitive diagnostic tools that can distinguish morphology and dignity, surgical treatment is not standardized yet. In conjunction with a case report, we summarize and critically compare current treatment strategies.

Abstract
PURPOSE To retrospectively evaluate the contribution of MRI to the diagnosis of arrhythmogenic right ventricular dysplasia (ARVD). PATIENTS AND METHODS Thirty two men and 18 women (mean age: 48.7 years) were imaged using gated spin echo scans and short axis cine MR. References were McKenna criteria (gold standard), and also what we called "strong presumption" which may correspond to early or localized patterns, but correspond to negative McKenna scores. RESULTS One patient was claustrophobic; another one was lost to follow-up. In reference to McKenna score, diagnosis of ARVD was established in 12 patients (2 of whom had familial dilated biventricular cardiomyopathy with rhythmic expression). Sensitivity, specificity, positive predictive value, negative predictive value and prevalence were respectively: 75%, 75%, 50%, 90% and 25%. Using "strong presumption" criteria, we observed 14 true positives (with sensitivity of 82%, specificity of 87%, PPV of 78%, NPV of 90% and prevalence of 35%). CONCLUSION In our group, MRI was always performed before angiography. In our series, right ventricular wall T1W hyperintensity was the most frequent finding.

Abstract
BACKGROUND Lipomatous hypertrophy of the interatrial septum (LHIS) is a benign disorder characterized by fat accumulation in the interatrial septum. It typically occurs in elderly, obese patients and may cause arrhythmia. OBJECTIVES The purpose of this study was to determine the imaging features of this cardiac pathology using multislice CT (MSCT), and its relationship with clinical findings. MATERIALS AND METHODS A total of 1,292 consecutive patients who underwent MSCT of the thorax from September 2001 to August 2002 were prospectively studied. Beside the analysis of patient records, the amount of fat in the interatrial septum, and its size and shape were determined. RESULTS Among the 1,292 patients investigated, we found 28 (2.2%) with LHIS. The mean age of affected patients was 72.2 years. MSCT studies revealed a mass of fat attenuation with sharp margins and sparing of the fossa ovalis, resulting in a dumbbell shape in all patients. The median thickness of the interatrial septum was 32 mm (range, 20 to 62 mm), and the median craniocaudal extend was 62 mm (range, 51 to 89 mm). Twenty-one patients (75.0%) showed increased epicardial fat, 18 patients (64.3%) had significant pulmonary emphysema, and 13 of 21 patients (61.9%) showed ECG abnormalities. Three patients underwent functional cardiac MRI studies. In one patient, hemodynamic obstruction by LHIS was shown. CONCLUSIONS MSCT scanning is a useful method to diagnose LHIS, a cardiac condition that in our series reached a 2.2% incidence. The lesion shows characteristic features, thus differentiating it from other cardiac tumors. Advanced age, obesity, pulmonary emphysema, and atrial arrhythmias are common additional findings in patients with LHIS.

Abstract
The focus to date of MDCT has been primarily on CT applications for evaluating the coronary arteries, notably the measurement of coronary artery calcification, plaque characterization, and atherosclerotic lumen stenosis. This is because of the limited temporal resolution of CT, and the recent rapid improvements in MRI for cardiac applications. However, if the temporal resolution of MDCT can be improved, there will be a compelling argument for undertaking further CT validation studies. Feasibility of CT has already been established by EBT for general cardiac diagnosis. Modifications for MDCT include improved software methods for post processing ECG-gated scan data or higher speed CT hardware for faster image acquisition, both of which are being developed at this time. EBT is also evolving and continuously being refined so that the new generation of scanners have exposure times of 50 msec or less. There are many considerations in comparing the pros and cons of competing cardiac imaging modalities. Published diagnostic validations studies, convenience, procedure time, the comfort level (of patients and physicians), availability, and cost are all critical. The level of acceptance and the accuracy with which specific patient management questions can be appropriately answered are crucial issues in determining which diagnostic procedure to perform. However, the jury is still out regarding the ultimate role of CT in the diagnosis of heart disease; certainly the great potential of cardiac CT has not yet been fully realized.

Abstract
This article describes the characteristic imaging findings and correlates them with the pathology in the nonfatty regions of benign atypical lipomatous tumors, which have different findings compared with typical lipomas and well-differentiated liposarcomas. For differentiating these tumors from typical lipomas and well-differentiated liposarcomas, it may be helpful to analyze nonfatty regions in benign atypical lipomatous tumors.

Abstract
BACKGROUND Little is still known concerning subcutaneous adipose tissue and cellulite, and controversial questions are still under discussion. AIMS Magnetic resonance imaging and spectroscopy were used to address two unresolved questions relating to the anatomy and physiology of subcutaneous adipose tissue. METHODS Using high spatial resolution magnetic resonance imaging we characterized the topography of the dermo- hypodermal junction, and the three-dimensional architecture of the subcutaneous fibrous septae. Using proton spectroscopy, we measured water and lipid fractions within a fat lobule, and T1 and T2 values of the detected compounds. All these data were analysed according to sex and presence of cellulite. RESULTS MR imaging quantified deeper indentations of adipose tissue into the dermis, and evidenced for the first time a great increase in the thickness of the inner fat layer in women with cellulite. Moreover, 3D reconstruction of the fibrous septae network showed a higher percentage of septae in a direction perpendicular to the skin surface in women with cellulite; but our study also depicted the tortuous aspect of this network. MR proton spectroscopy could not show any differences related to sex or presence of cellulite concerning T1 and T2 relaxation times of the detected compounds within a fat lobule, neither the unsaturated lipid fraction, the saturated lipid fraction, nor the water fraction. CONCLUSIONS Magnetic resonance imaging showed that the 3D architecture of fibrous septae couldn't be modelled simply as perpendicular planes for women and tilted planes at 45 degrees for men. MR spectroscopy did not confirm the hypothesis of increased water content in the adipose tissue of women with cellulite as suggested by others, except if such water would be located in the connective septae.

Abstract
Involuted intraosseous lipoma with extensive fat necrosis resulting in cyst formation (Milgram stage III) is distinguishable from lesions without necrosis (stage I) or lesions with focal fat necrosis (stage II), based on differences in signal intensity on magnetic resonance imaging (MRI). Fat tissue has a high signal intensity on both T1- and T2-weighted MR images, whereas the extensive fat necrosis that results in cyst formation shows high signal intensity on T2-weighted images and low intensity on T1-weighted images. We report a patient in whom an intraosseous lipoma with high signal intensity on both T1- and T2-weighted MRI was found to be extensively involuted on histopathologic examination. Intraosseous lipoma appears to undergo spontaneous involution. In some patients, therefore, surgical excision may not be necessary. A correct preoperative diagnosis should reduce the necessity for a biopsy or surgery. Although lesions classified as stage I or II are easily identified by MRI, those of stage III are difficult to diagnose preoperatively by this method.
