Idiopathic Tumoral Calcinosis

Abstract

Teaching Point: The imaging clues to differentiate idiopathic tumoral calcinosis from other calcified soft tissue lesions include: pseudotumoral appearance with mass effect, bone erosion with intra-osseous protrusion of calcification, lobulated morphology, and peri-articular location on the extensor side.
