Abstract:
Background:
Monomorphic epitheliotropic intestinal T-cell lymphoma (MEITL) is a rare, rapidly progressive, primary intestinal T-cell lymphoma. The most
common site of occurrence is on the small intestine. The prognosis of MEITL is extremely poor due to delayed diagnosis and lack of targeted
therapy.
Case Summary:
A case of MEITL involving the entire small bowel, part of the colon, rectum, mesenteric lymph nodes, and liver is herein reported. We are
presenting the 18F-FDG PET/CT features of MEITL, which showed all involved lesions with increased FDG activity. The MRI and pathological
characteristics of MEITL were also described. Furthermore, some malignant diseases and benign diseases should be considered in the differential
diagnosis.
Conclusion:
Based on the lesions with a high accumulation of FDG, our case shows the involved extent of MEITL, which is helpful for biopsy and treatment
option decisions. We expect more could know about this disease and make an early diagnosis to improve the outcomes of MEITL.
