This study aimed to investigate the characteristic features of CT images of diffuse tenosynovial giant cell tumor (D-TSGCT) from the temporomandibular joint (TMJ) to understand CT imaging diagnosis of the disease.
CT images and clinical information from 10 patients with D-TSGCT of TMJ were recruited for retrospective analysis from March 2013 to March 2017 in Peking University Hospital of Stomatology. All cases were treated by surgery and confirmed by pathology.
CT scan demonstrated hyperdense soft-tissue masses and various kinds of calcification in all of the 10 subjects. Contrast-enhanced scan exhibited obvious enhancement in six patients. Bone destruction of the mandibular condyles and skull base was found in seven and six subjects, respectively.
CT appearance of D-TSGCT of the TMJ is characterized by hyperdense soft tissue with calcification, further enhancement in contrast-enhanced scan, and bone destruction in the mandibular condyles and skull base in some cases.
本研究旨在探讨颞下颌关节弥漫性腱鞘巨细胞瘤（D-TSGCT）的CT图像特征，以了解该疾病的CT影像诊断。
回顾性分析2013年3月至2017年3月在北京大学口腔医院就诊的10例颞下颌关节D-TSGCT患者的CT图像及临床资料。所有病例均接受手术治疗并经病理证实。
10例患者CT扫描均显示高密度软组织肿块及多种钙化。增强扫描6例有明显强化。分别有7例和6例发现下颌骨髁突及颅底骨质破坏。
颞下颌关节D-TSGCT的CT表现为高密度软组织伴钙化，增强扫描有进一步强化，部分病例下颌骨髁突及颅底有骨质破坏。
