Giant Joints in Association with Chronic Renal Failure

Tumoral Calcinosis (TC) is an uncommon benign entitiy characterized by solitary or multiple tumorlike densely calcified periarticular masses located typically in the extensor surfaces of the large joints. TC can be primary or secondary. The primary TC is a rare hereditary familial disorder of phosphate regulation. On the other hand, secondary TC is associated with an underlying disease, most frequently, chronic renal faliure (CRF). Herein, we present a case of 40 year old male patient with CRF and 10 years history of hemodialysis, presenting with swellings around the right hip and left shoulder joints. The diagnosis of secondary TC has been made with typical computed tomography (CT) and magnetic resonance imaging (MRI) findings. Secondary TC is an uncommon condition particularly occuring in association with CRF. Typical radiologic findings and clinical history are leading in the diagnosis and prevent unnecessary further evaluations.
