Case report reveals symmetrical distal peripheral intramedullary FDG uptake in a patient with diffuse large B-cell lymphoma, highlighting an atypical skeletal presentation.
A 74-year-old woman was referred for 18 F-FDG PET/CT scanning to investigate an underlining etiology due to recently developed unexplained bone pains and lack of walking capacity. On the initial PET/CT scan, we have noted a highly symmetrical and apparent intramedullary FDG uptake of the distal parts of appendicular skeleton system including the bilateral elbows, wrists, and foot ankles in addition to a lymphadenomegaly in the right groin. The excisional biopsy from the lymph node of right groin revealed a diagnosis of diffuse large B-cell lymphoma.
