A pictorial review of primary synovial osteochondromatosis

Abstract

Primary synovial osteochondromatosis has a variety of radiological appearances ranging from the pathognomonic plain film appearances to the more unusual non-mineralised extraarticular manifestation of the disease. The less common manifestations of the disease require multimodality imaging to make the diagnosis. CT and MRI are particularly useful in fully characterising primary synovial osteochondromatosis and to allow for appropriate surgical planning to minimise disease recurrence.
