A case of a patient with a malignant schwannoma, who was originally diagnosed as having internal derangement of the temporomandibular joint (TMJ), is presented. This is only the second reported case of this tumor with TMJ symptoms. The importance of obtaining adequate TMJ radiographs as part of the initial data collection process is stressed. Computed tomography (CT) and magnetic resonance imaging (MRI) scans are suggested if the patient has any of the ominous signs or symptoms mentioned in the text. When a patient is initially diagnosed with TMJ disease, failure to respond to appropriate therapy should alert the clinician that the initial diagnosis may be incorrect.
本文介绍了一例最初被诊断为颞下颌关节（TMJ）内紊乱的恶性神经鞘瘤患者。这是该肿瘤出现TMJ症状的第二例报告病例。强调了在初始数据收集过程中获取足够的TMJ X光片的重要性。如果患者出现文中提到的任何不祥体征或症状，建议进行计算机断层扫描（CT）和磁共振成像（MRI）扫描。当患者最初被诊断为TMJ疾病时，对适当治疗无反应应提醒临床医生初始诊断可能不正确。
