Osteopoikilosis and chondrocalcinosis.

Osteopoikilosis is a benign and rare disorder characterized by abnormal calcium phosphate deposition in the articular cartilage. It usually is an incidental radiologic finding. Chondrocalcinosis is characterized by calcium pyrophosphate deposition in the articular cartilage. Both diseases can be asymptomatic. We describe some radiographic features that distinguish osteopoikilosis from other similar conditions and report a young female patient with osteopoikilosis associated with chondrocalcinosis. To the best of our knowledge, this is the first time these processes have been found in the same patient.
