PurposeTo evaluate the types of synovial condromatosis (SC) of tempromandibular joint (TMJ) on MRI and their potential aggressive behavior.Methods144 patients with pure SC of TMJ were included in. On MRI, 3 types of the lesion included loose body, homogeneous mass, and mixture of both loose body and homogeneous mass. Bony evaluations included 4 stages of erosion: without erosion, chondral breakdown, bony absorption and bony perforation.Results47 (32.6%) cases were categorized in the type of loose body, 71 (49.3%) cases in the type of homogeneous mass, and 26 (18.1%) cases in the type of mixture. 80% of bony perforation belonged to the type of homogeneous mass and 20% belonged to the type of mixture. 2 patients were found recurrence.ConclusionThe types of homogeneous mass and mixture of both on MRI were more aggressive. Homogeneous mass with bony erosion on MRI had potential recurrence.
