摘　　要：目的探讨颞骨巨细胞修复性肉芽肿（GCRG）的cT及MRI表现。方法对14例经手术切除的颞骨GcRG患者的影像学特征进行回顾性分析，并复习相关文献。结果14例GCRG行cT及MRI检查。CT检查示软组织肿块影，邻近骨质呈溶骨性、膨胀性破坏。MRI检查示病变呈长T1、短T2信号，DWLK低信号，增强扫描明显不均匀强化。病理学诊断巨细胞修复性肉芽肿。所有病例随访3个月至4年，其中有1例出现复发，再次手术后随访3个月无复发。结论颞骨GCRG的影像学表现具有一定的特征性，结合临床资料、病理及实验室检查结果，可做出正确诊断，术后需长期随访。Objective To explore the CT and MRI manifestations of temporal bone giant cell reparative granuloma. Methods 14 cases of patients after surgical removal of the temporal bone GCRG imaging features were retrospectively analyzed, and relevant literatures were reviewed. Results 14 cases of GCRG were examined by CT and MRI. CT examination found soft tissue mass, and adjacent bone was found osteolytic and expansive desctruction. MRI showed fhat lesions had short T1 and long T2 signal, and low DWI signal, with enhancement scan obviously more uneven. Pathology was used to diagnose giant cell reparative granuloma. All cases were followed up for 3 months to 4 years. One case relapsed, but did not recur again after the operation in 3 follow-up months. Conclusion Temporal bone GCRG have certain characteristic imaging features. Combined with clinical data, pathological and laboratory test results, GCRG image manifestations can used to make correct diagnosis, but postoperative long-term follow-up is needed.
