FDG PET/CT detects intense external iliac vein uptake leading to venous angiosarcoma diagnosis.
FDG PET/CT can incidentally detect rare venous angiosarcomas during post-therapy surveillance for lymphoma.
Incidental venous FDG avidity on lymphoma surveillance PET/CT may signal angiosarcoma; leaves open its impact on routine imaging protocols.
A 56-year-old man with diffuse large cell lymphoma underwent posttherapy F-18 fluorodeoxyglucose positron emission tomography/computed tomography (FDG PET/CT). A new focus of intense uptake was detected in contact with the left external iliac vein. This was biopsied and diagnosed as an angiosarcoma of the external iliac vein.

Eugene Lin (2008) studied this question. FDG PET/CT imaging detected a new focus of intense uptake in the left external iliac vein, leading to the biopsy and diagnosis of a venous angiosarcoma.
