Tumours of the temporomandibular joint (TMJ) often mimic common conditions of the TMJ, such as TMJ dysfunction syndrome, leading to a delay in the diagnosis. Chondrosarcoma of the TMJ is a rare tumour, with only 18 cases described in the literature. The initial surgical attempt at removal is of important, as aggressive excision offers the best chance for successful treatment. Chondrosarcoma present at the surgical resection margins has a poor prognosis. We present a case of chondrosarcoma of the right TMJ. In our case, combined diagnostic techniques consisting of a panoramic radiograph, computed tomography (CT) and magnetic resonance imaging (MRI) made an accurate preoperative assessment possible and significantly influenced the treatment provided.
颞下颌关节（TMJ）肿瘤常与 TMJ 的常见病症相似，例如 TMJ 功能紊乱综合征，导致诊断延迟。TMJ 软骨肉瘤是一种罕见的肿瘤，文献中仅描述了 18 例。初次手术切除非常重要，因为积极的切除为成功治疗提供了最佳机会。在手术切除边缘处发现的软骨肉瘤预后较差。我们报告了 1 例右侧 TMJ 软骨肉瘤。在我们的病例中，结合使用全景 X 线摄影、计算机断层扫描（CT）和磁共振成像（MRI）等诊断技术，可在术前进行准确评估，并显著影响所提供的治疗。
