Extensive Extranodal Involvement of Rare Sites in Non Hodgkin’s Lymphoma Detected on 18F- FDG PET-CT: A Case Report

摘要

We present a case of a 23 year-old male treated for Hodgkin’s lymphoma who developed diffuse large B-cell lymphoma (DLBCL) 8 years after achieving remission. 18F-fluorodeoxyglucose positron emission tomography computed tomography (18F-FDG PET-CT) was done, which revealed extensive extranodal involvement of bilateral atria, bilateral kidneys, ileo-caecal junction and left testis along with mesenteric and retroperitoneal lymph nodal involvement. Renal and cardiac lesions were not detected by contrast-enhanced CT. Simultaneous lymphomatous involvement of rare sites such as heart, kidneys and testis in a single patient has not been reported before.
