Four rare extranodal sites seen on FDG PET/CT in a single patient of disseminated lymphoma.

Extranodal disease refers to lymphomatous infiltration of anatomic sites other than lymph nodes. With the advent of FDG PET/CT for staging, rare sites of extranodal disease have been documented. We report a case of Non- Hodgkin's lymphoma with four rare extranodal sites, namely adrenal, peripheral nerves, pancreas and prostate, in the same patient, detected on FDG PET/CT imaging.
