Pigmented villonodular synovitis of the temporomandibular joint.
Pigmented villonodular synovitis (PVNS) rarely occurs in the temporomandibular joint. The bony changes are easily assessed by tomography. Pluridirectional tomography cannot, however, evaluate the soft tissue component of the lesion especially that medial to the mandibular condyle. This area is accessible to CT scan evaluation. A case is presented in which the medial extent of the lesion was determined by CT scan. The radiologic findings of PVNS of the temporomandibular joint are discussed.
