Abstract

ABSTRACT: We describe the 18F-fluorodeoxyglucose positron emission tomography/contrast enhanced computed tomography (FDG PET/CECT) images of a 63-year-old male who complained of back pain and was suspected of multiple myeloma based on magnetic resonance imaging. PET/CECT suggested the FDG avid lesion involving prostate, accompanied by multiple lytic skeletal lesions with no evidence to suggest other possible primary site. A bone marrow biopsy suggested a metastatic adenocarcinoma of primary prostatic origin. Post anti-androgen therapy follow-up FDG PET/CT revealed reductions in the metabolic activities and soft tissue components of most of the metastatic skeletal lesions. These images highlight the possible indication of FDG PET/CT in evaluation of prostatic malignancy in era of 68Ga-PSMA.
