18F-FDG uptakes around right shoulder with osteoarthritis. a Frontal radiograph of the right shoulder shows glenohumeral joint OA with joint space narrowing and osteophyte formation. b Axial CT image at the level of the glenohumeral joints shows severe right glenohumeral joint space narrowing and osteophytosis, compatible with advanced OA. c MIP image from 18F-FDG PET-CT scan shows pathologic radiopharmaceutical accumulation around the right glenohumeral joint. d Fused axial and coronal PET-CT images show hypermetabolic activity along the periphery of the right glenohumeral joint in the expected location of the synovium and joint capsule, compatible with synovitis associated with OA
