摘要:

目的 探讨颞下颌关节弥漫型腱鞘巨细胞瘤CT影像的特征性表现,提高对该疾病的认识及影像诊断能力。方法 回顾性分析北京大学口腔医院2013年3月—2017年3月收治的10例经手术及病理诊断为颞下颌关节弥漫型腱鞘巨细胞瘤患者的CT表现及临床资料。结果 10例患者均表现为高密度软组织肿块伴不同程度钙化,6例患者的增强扫描影像均表现为显著强化,7例患者出现髁突骨质吸收或破坏,6例患者伴有颅底骨质破坏。结论 颞下颌关节弥漫型腱鞘巨细胞瘤的CT特征表现为高密度软组织肿块伴钙化和显著强化,可伴有髁突和颅底骨质的吸收或破坏。

Abstract:

Objective 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. Methods 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. Results 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. Conclusion 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.
