A 62-year-old male with known prostate cancer underwent 18F- uorodeoxyglucose positron emission tomography/ computed tomography (18F-FDG PET/CT) scan for suspected osseous metastases after a magnetic resonance imaging of the pelvis, done for chronic low back pain and demonstrated a number of suspicious T1 hypointense/T2 hyperintense lesions in the sacrum, iliac bones and right proximal femur.18F-FDG PET/CT showed abnormal foci of increased tracer uptake in the sacrum, iliac bones and right proximal femur. Core biopsies from the sacrum were performed, showing intertrabecular non-caseating granulomata with surrounding small lymphocytes. Acid-fast bacilli and Gomori methenamine silver stains were negative, consistent with intraosseous sarcoidosis.

Key words: 18F- uorodeoxyglucose positron emission tomography/computed tomography, non-caseating granulomata, sarcoidosis
