[PMID: 39649901 PMCID: PMC11623860 DOI: 10.1097/ms9.0000000000002658] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2024] [Accepted: 09/15/2024] [Indexed: 12/11/2024] Open
Abstract
Introduction and importance Deep-located glomangiomas are rarely reported. Because of their scarcity, treatment strategy is hard to establish. Herein, the authors report the first case to our knowledge of pre-sacral glomangioma. Case presentation A 34-year-old female patient, with no previous medical history, consulted for 2-month-old pelvic abdominal pain, vomiting and delayed menstruation. Her physical and biological parameters were with no abnormalities. MRI of the pelvis demonstrated a 14 cm mixed heterogeneous pre-sacral lesion pushing the rectum anteriorly. She was operated on via a laparoscopic approach. Division of Douglas' pouch and pelvic peritoneum laterally to the bladder showcased a cystic lesion of 13×8 cm occupying the pelvis while deviating the rectum anteriorly. Its content was aspirated and left membrane was extracted in a sac. The postoperative course was uneventful. Discussion Pre-sacral masses are hard to treat because of their large heterogeneity. Surgical resection should be tempted to retrieve the definitive histological diagnosis and relieve the patient. However, the surgical route is controversial as each approach has its advantages. Thus, the surgical route should take into consideration the lesion's size, height and surrounding contacts, the patient's functional state and surgeon's expertise. Conclusion Pre-sacral glomangiomas carries a low malignant pattern but should be resected to offer histological diagnosis. The surgical route remains at the surgeon's decision, with the main objective to totally resect the encountered lesion without causing functional and sexual complications or harm to surrounding viscera.

Abstract
Large retrorectal tumors are rare and often a diagnostic and surgical challenge due to their anatomical location. We report the case of a 55-year-old patient with weight loss and changed bowel habits, where digital rectal examination revealed a retrorectal mass raising suspicion of a tumor. Magnetic resonance imaging (MRI) and computed tomography (CT) showed a large retrorectal tumor and histopathology after surgical resection showed undifferentiated spindle cell sarcoma. This tumor type has not been previously reported as the etiology of large retrorectal tumors. We discuss the implications of diagnostic imaging, especially MRI, in the approach to diagnosis and surgical treatment of retrorectal tumors with reference to the scientific literature and previously reported cases of retrorectal tumors.

Abstract
An epidermal cyst, also known as an epidermoid cyst or epidermal inclusion cyst, is the most prevalent type of cutaneous cyst. This noncancerous lesion can appear anywhere on the body, typically presenting as an asymptomatic dermal nodule with a visible central punctum. In the case presented herein, an epidermal cyst with uncommon features was misdiagnosed as a lymphatic malformation based on preoperative magnetic resonance imaging (MRI). A 61-year-old man came to us with a swollen left cheek that had been present for 11 months. The preoperative MRI revealed a 3 × 3.8 × 4.6 cm lobulated cystic lesion with thin rim enhancement in the left masticator space. The initial differential diagnosis pointed toward a lymphatic malformation. We proceeded with surgical excision of the lesion via an intraoral approach, and the specimen was sent to the pathology department. The pathological diagnosis revealed a ruptured epidermal cyst, indicating that the initial diagnosis of a lymphatic malformation based on preoperative MRI was incorrect. Epidermal cysts located under the muscle with no visible central punctum are uncommon, but should be considered if a patient presents with facial swelling.

Abstract
BACKGROUND Cystic tumors in the presacral space represent a rare pathology. In case of symptoms, but particularly due to the danger of malignant degeneration, surgical removal is indicated. Due to the complex position in the pelvis with its proximity to important anatomic structures, the choice of the surgical approach is decisive. METHODS To present an overview of the recent knowledge of presacral tumors, a PubMed-based literature review was performed. Subsequently, we present 5 cases where different surgical strategies were evaluated including a video of a laparoscopic removal. RESULTS Presacral tumors can be of different histopathologic origins. Complete surgical excision is the treatment of choice, with open abdominal, open abdominoperineal, and posterior accesses available, as well as minimally invasive techniques. CONCLUSION Laparoscopic resection of presacral tumors is a well-suitable option, but the decision must always be made individually.

Abstract
The complex anatomy and similarity of imaging features of various pathologies in the pelvis can make accurate radiology interpretation difficult. While prompt recognition of ovarian cancer remains essential, awareness of processes that mimic ovarian tumors can avoid potential misdiagnosis and unnecessary surgery. This article details the female pelvic anatomy and highlights relevant imaging features that mimic extra-ovarian tumors, to help the radiologists accurately build a differential diagnosis of a lesion occupying the adnexa.

Abstract
BACKGROUND Tailgut cysts (TGCs) are benign congenital abnormalities that usually present with non-specific symptoms, constituting a diagnostic dilemma for physicians. The aim of this study was to systematically review the literature concerning clinical manifestations, diagnostic modalities and histologic findings of TGCs and highlight current knowledge on therapeutic management of this rare entity. METHODS PubMed and Embase databases were systematically searched by two independent investigators (last search 18 February 2021) for studies concerning TGCs published in the past two decades. RESULTS Totally, 144 articles, including 135 case reports and 9 case series, met our inclusion criteria. One hundred eighty-four patients were included (3:1/female:male) with an age of 42.3 ± 18.7 years (mean, SD), while 5 cases concerned new-born infants. Pain was the prevailing clinical manifestation (41.8%), whereas 16.8% were asymptomatic. MRI and CT were utilized for diagnosis in 58.7% and 54.7% of cases, respectively. The majority of cysts were multilocular, while ciliated columnar epithelium and smooth muscles of the cyst wall were the prevailed histological findings. Malignant degeneration of TGCs was reported in 32.1% of cases, while carcinoid tumours were the most frequent malignancies. Surgical resection was performed in 155 cases, while laparoscopic and robotic approach was preferred in 18 and 2 cases, respectively. A posterior approach was implemented in 80.9%, anterior technique in 9% and combined technique in 6.7% of cases. Postoperative complications and recurrence of the cystic lesion were reported in 17.4% and 7.6% of cases, respectively. CONCLUSIONS TGCs constitute a dilemma for the physicians. Surgical resection comprises the ultimate treatment to avoid complications or malignant transformation of the cyst. Concrete follow-up strategies and optimal therapeutic options should be outlined through consensus guidelines and at the time being, such decisions can be made only on the basis of extrapolation and on a case-by-case approach.

Abstract
Schwannomas also known as neurilemomas are benign tumors. Retrorectal schwannomas are extremely rare, accounting for 1 to 5% of all schwannomas. They are mostly asymptomatic but may present with symptoms such as pelvic pain, back pain, lower extremities pain, or constipation. Physical examination is often poor. Imaging (CT, MRI) and fine needle biopsy can often help orient the diagnosis. The treatment of choice is monoblock resection of the mass. The prognosis is good. Recurrence has been reported especially after intralesional enucleation. We report a case of a 41-year-old male patient consulting for chronic low back pain eventually diagnosed with retrorectal schwannoma. We performed a surgical resection and the histological examination was consistent with the diagnosis of benign (ancient) schwannoma.

Abstract
Introduction and importance: Retrorectal cystic hamartoma (RCH) is a rare congenital lesion of the presacral space, which is part of the vestigial cystic tumors often benign and predominantly in women. Generally asymptomatic, the appearance of symptoms such as pain or neurological disorders should raise suspicion of degeneration. Case presentation We report an unusual observation of a 62-year-old patient admitted for perineal pain evolving for 2 months associated with tenesma and chronic constipation. The digital rectal examination found a posterior bulge at 4 cm from the anal margin, without intraluminal lesion. Rectosigmoidoscopy had noted posterior extrinsic compression but no rectal tumor. Pelvic CT and MRI had shown a solidocystic formation of the retro-rectal and presacral spaces, related to an enteric cyst. The operation was performed by abdominal approach and the surgical exploration had found a bilobed cystic formation. The cystic mass was removed and the anatomopathological examination concluded that it was a cystic hamartoma with no sign of malignancy. Clinical discussion Retrorectal tumors develop in the space bounded anteriorly by the propria fascia of the rectum and posteriorly by the presacral fascia overlying the sacrum. Common in children and then often malignant, inversely, in adults, they are rare and most often benign tumors. They are generally asymptomatic with a predominance of females, unlike our observation where the patient was male with a symptomatology dominated by perineal pain and constipation. The discovery is incidental in the majority of cases, however, in some cases, these cysts may be revealed by complications. The lesion can be explored by transrectal or suprapubic ultrasound, MRI and CT scan. Rectoscopy and fistulography may complete the exploration in case of diagnostic doubt. The resection must be thorough and in monobloc because of the risk of recurrence and the approach depends on the location and the size of the lesion. Conclusion RCH is a rare benign lesion whose morphological characteristics seem quite stereotyped. A detailed postoperative anatomopathological examination allows the diagnosis to be made and, above all, to look for a site of malignant transformation. This is why a complete surgical removal is necessary to prevent recurrence.

Abstract
Background Neuroendocrine tumors (NETs) originate from neuroendocrine cells, which are found throughout the body. NETs occur principally in the gastrointestinal tract (approximately 65%) and bronchopulmonary tract (approximately 25%) but rarely occur in the presacral space. Aside from primary and metastatic lesions, there have been reports of NETs occurring in the presacral space arising from tailgut cysts, teratomas, and imperforate anus. We herein report a rare case of laparoscopic resection of a NET in the presacral space, which almost fully replaced tailgut cysts. Case presentation A 68-year-old woman was referred to our hospital for surgery of a right inguinal hernia, but preoperative computed tomography revealed an asymptomatic 43-mm mass in the presacral space. Magnetic resonance imaging showed a multilocular solid mass with clear boundaries and a slightly high signal intensity on T1- and T2-weighted images. Positron emission tomography showed 18F-fluorodeoxyglucose uptake. Thus, we suspected a malignant tumor and performed laparoscopic resection to obtain a definitive diagnosis. Macroscopically, the tumor was 43 mm in size with clear boundaries, and the cut surface was a gray-white solid component. Histopathological findings revealed that the tumor was composed of relatively uniform cells with fine chromatin, with round to oval nuclei arranged in solid, trabecular, or rosette-like growth patterns. Small cysts lined with stratified squamous epithelium and columnar epithelium were observed along with solid components of the tumor, which is a feature of tailgut cysts. Therefore, the final diagnosis was NET Grade 1 arising from tailgut cysts. No recurrence was observed within 1 year after surgery. Conclusions We performed en bloc laparoscopic resection of a NET arising from tailgut cysts in the presacral space without injury. In cases of a solid lesion in the presacral space, not only the primary disease but also the pathological condition with tissue transformation and replacement should be considered, as in this case.

Abstract
Pelvic masses can present a diagnostic challenge owing to the difficulty in assessing their origin and the overlap in imaging features. The majority of pelvic tumors arise from gastrointestinal or genitourinary organs, with less common sites of origin including the connective tissues, nerves, and lymphovascular structures. Lesion evaluation usually starts with clinical assessment followed by imaging, or the lesion may be an incidental finding at imaging performed for other clinical indications. Since accurate diagnosis is essential for optimal management, imaging is useful for suggesting the correct diagnosis or narrowing the differential possibilities and distinguishing tumors from their mimics. Some masses may require histologic confirmation of the diagnosis with biopsy and/or up-front surgical resection. In this case, imaging is essential for presurgical planning to assess mass size and location, evaluate the relationship to adjacent pelvic structures, and narrow differential possibilities. Pelvic US is often the first imaging modality performed in women with pelvic symptoms. While US is often useful to detect a pelvic mass, it has significant limitations in assessing masses located deep in the pelvis or near gas-filled organs. CT also has limited value in the pelvis owing to its inferior soft-tissue contrast. MRI is frequently the optimal imaging modality, as it offers both multiplanar capability and excellent soft-tissue contrast. This article highlights the normal anatomy of the pelvic spaces in the female pelvis and focuses on MRI features of common tumors and tumor mimics that arise in these spaces. It provides an interpretative algorithm for approaching an unknown pelvic lesion at MRI. It also discusses surgical management, emphasizing the value of MRI as a road map to surgery and highlighting anatomic locations where surgical resection may present a challenge. ©RSNA, 2019.

Abstract
Management of large-size retrorectal gastrointestinal stromal tumors (GISTs) is complex and challenging from diagnosis to treatment. This may create technical difficulties in surgical access and complete resection of the tumor. The abdominosacral resection has the benefit of improved visualization via the anterior incision, with enhanced exposure of the midrectal area, which makes resecting the tumor completely via the posterior approach easier. We report 2 cases of patients with a retrorectal GIST and neurofibromatosis type 1, one in a 27-year-old woman with a defecation complaint and the other in a 58-year-old woman with a defecation and urination complaint. Based on the anatomical pathology, both patients were diagnosed with a GIST. The tumors were excised via an abdominosacral resection. Retrorectal GISTs are rare, and abdominosacral resection allows complete resection of a large-size retrorectal GIST with low morbidity and an absence of functional impairment. The abdominosacral resection should be considered in certain situations.

Toh JWT, Morgan M. Management approach and surgical strategies for retrorectal tumours: a systematic review. Colorectal Dis 2016; 18:337-50.

Abstract
AIM The management strategy for retrorectal tumours is complex. Due to their rarity, few surgeons have expertise in management. METHOD A systematic literature review was conducted using the PubMed database. English language publications in the years 2011-2015 that assessed preoperative management, surgical strategies and chemoradiotherapy for presacral tumours were included. Two hundred and fifty-one abstracts were screened of which 88 met the inclusion criteria. After review of the full text, this resulted in a final list of 42 studies eligible for review. RESULTS In all, 932 patients (63.2% female, 36.8% male; P < 0.01) with a retrorectal tumour were identified. Most were benign (65.9% vs. 33.7%, P < 0.01). Imaging distinguished benign from malignant lesions in 88.1% of cases; preoperative biopsy was superior to imaging in providing an accurate definitive diagnosis (91.3% vs. 61.4%, P < 0.05) with negligible seeding risk. Biopsy should be performed in solid tumours. It is useful in guiding neoadjuvant therapy for gastrointestinal stromal tumours, sarcomas and desmoid type fibromatosis and may alter the management strategy in cases of diffuse large B-cell lymphoma and metastases. Biopsies for cystic lesions are not recommended. The gold standard in imaging is MRI. The posterior Kraske procedure is the most common surgical approach. Overall, the reported recurrence rate was 19.7%. CONCLUSION This review evaluated the management strategies for retrorectal tumours. A preoperative biopsy should be performed for solid tumours. MRI is the most useful imaging modality. Surgery is the mainstay of treatment. There is limited information on robotic surgery, single-port surgery, transanal endoscopic microsurgery, chemoradiotherapy and reconstruction.

Abstract
Our objective is to describe an approach for retrorectal/presacral mass evaluation on imaging with attention to imaging features, allowing for refinement of the differential diagnosis of these masses. Elaborate on clinically relevant features that may affect biopsy or surgical approach, of which the radiologist should be aware. A review of current literature regarding the diagnosis and treatment of retrorectal/presacral masses was performed with attention to specific findings, which may lend refinement to the differential diagnosis of these masses. Cases were obtained by searching through a radiology database at a single institution after Institutional Review Board approval. Recent advances in imaging and treatment methods have led to the increased role of radiology in both imaging and tissue diagnosis of retrorectal masses. Surgical philosophies surrounding the treatment of these masses have not significantly changed in recent years, but there are a few key factors of which the radiologist must be aware. The radiologist can offer refinement of the differential diagnosis of retrorectal masses and can elaborate on salient findings which could alter the need for neoadjuvant chemoradiation therapy, pre-surgical tissue diagnosis and surgical approach. This article presents an imaging approach to retrorectal/presacral masses with emphasis on findings which can dictate the ultimate need for neoadjuvant therapy and pre-surgical tissue diagnosis and alter the preferred surgical approach. This article consolidates key findings, so radiologists can become more clinically relevant in the evaluation of these masses.
