Abstract

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.

摘要

色素沉着绒毛结节性滑膜炎（PVNS）很少发生于颞下颌关节。通过体层摄影术很容易评估骨质改变。然而，多向体层摄影术无法评估病变的软组织成分，尤其是下颌髁突内侧的软组织成分。CT扫描可以评估该区域。本文报告1例通过CT扫描确定病变内侧范围的病例。并对颞下颌关节色素沉着绒毛结节性滑膜炎的影像学表现进行了讨论。
