Imaging findings of primary monomorphic epitheliotropic intestinal T-cell lymphoma: A case report

Table 1 Previous case reports of magnetic resonance and ¹⁸F-fluorodeoxyglucose positron emission tomography/computed tomography findings in monomorphic epitheliotropic intestinal T-cell lymphoma

Ref.	Age/sex	Symptom	Location	Imaging findings	Treatment	Outcome, month
[8]	48/F	Abdominal pain, diarrhea, distension, dysuria, frequency, and urgency	Entire small bowel, part of the colon, and rectum. Infiltration of the spleen, skeleton, liver and some mesenteric lymph nodes	Iso or hypo-intensity on T2WI, reduced diffusion on DWI, low signal intensity on ADC map, and markedly homogeneous enhancement. Increased FDG-uptake (SUVmax 4.0-10.2). The spleen, skeleton, liver and some swollen mesenteric lymph nodes were also FDG-avid	Only received anti-infection, nutrition support, and hormone therapy	3 (dead)
[9]	74/M	Acute onset of left hemiparesis and diarrhea	The small intestinal of the pelvic cavity. Involving the lung and brain	PET-MRI revealed high 18F-FDG accumulation in a mass in the pelvic cavity (SUVmax of 12.9), the right cerebral hemisphere with SUVmax of 8.3, bilateral lungs (SUVmax of 11), and mediastinal lymph nodes (SUVmax of 8.6)	Transferred to outpatient clinic for palliative care	Absent
[10]	57/M	Bloody diarrhea, abdominal pain, and urological symptoms, including dysuria, frequency and urgency	The ileocecum, entire colon, and rectum	Increased FDG activity (SUVmax of 14.5). Multiple pulmonary nodules and ground-glass opacities in both lungs with intense FDG uptake (SUVmax of 14.8) and abnormal hypermetabolism in the prostate (SUVmax of 5.6)	Chemotherapy	1.5 (dead)
[12]	56 (ranged 39-70)/8M, 4F	Abdominal pain, abdominal distension, ascites, intestinal obstruction, diarrhea, intestinal perforation, weight loss and gastrointestinal bleeding	The stomach, small bowel and large bowel. Lymph nodes and other organs were involved in 58% of cases. Thoracic and brain were frequently involved	The SUVmax of the stomach, small bowel and large bowel lesions varied from 3.6 to 8.7. The SUVmax of regional lymph nodes varying from 0.9 to 5.3	Chemotherapy	The median survival was 13 (1-136) months
[13]	61/M; 35/F	Upper abdominal pain and intermittent black stool; abdominal distention	Small intestine and upper sigmoid colon	Increased metabolism in 18F-FDG PET/CT. Regional lymph nodes were also metabolically active	CHOP combined with chidamide; surgery combined with ifosfamide, etoposide, and vincristine and chidamide	15 (dead); 17 (alive)

F: Female; M: Male; T₂WI: T₂ weighted imaging; DWI: Diffusion-weighted imaging; ADC: Apparent diffusion coefficient; CHOP: Cyclophosphamide, doxorubicin, vincristine, and prednisone; ¹⁸F-FDG PET/CT: ¹⁸F-fluorodeoxyglucose positron emission tomography/computed tomography; MRI: Magnetic resonance imaging; SUV: Standardized uptake value.
