F. Ontell et A. Greenspan, CHONDROSARCOMA COMPLICATING SYNOVIAL CHONDROMATOSIS - FINDINGS WITH MAGNETIC-RESONANCE-IMAGING, Canadian Association of Radiologists journal, 45(4), 1994, pp. 318-323
A 64-year-old man with a tender mass at the ankle was found to have ch
ondrosarcoma complicating synovial chondromatosis. Malignancy was susp
ected on the basis of the clinical presentation rather than the findin
gs in plain radiographs or magnetic resonance images. Chondrosarcoma a
rising in synovial chondromatosis is very rare. Misinterpreting the la
tter condition as malignant and the former as benign can be problemati
c, and the importance of distinguishing the two entities is discussed.
