| 目的探讨软组织透明细胞肉瘤的PET/CT特征。方法10例经病理证实的透明细胞肉瘤术前均行18F-FDG PET/CT检查,对肿瘤影像学表现及临床特征进行分析。结果10例患者原发病灶的最大标准化摄取值(SUVmax)平均值为6.52(5~9.6)。PET/CT发现肺转移7例,软组织转移5例,区域淋巴结转移3例,未发现骨、肝、脑转移；而相应的CT检查发现肺转移6例,软组织转移1例。结论软组织透明细胞肉瘤的18F-FDG PET/CT影像缺乏特异性,但可以更好地显示病变范围及转移情况,使分期更加准确、及时,有利于选择针对性的治疗方案。 |

| Abstract: |
| ObjectiveTo investigate the 18F-FDG PET/CT features of clear cell sarcoma (CCS) of soft tissue. MethodsTen patients with pathologically confirmed CCS were enrolled in the present study. All patients underwent preoperative 18F-FDG PET/CT scanning, and the image findings and clinical characteristics of the tumors were analyzed. ResultsThe mean maximum standard uptake value (SUVmax) of the primary lesions was 6.52(range, 5-9.6) in the patients. PET/CT revealed lung metastasis in 7 patients, soft tissue metastases in 5, and regional lymph node metastases in 3, with no brain/bone/liver metastases. CT findings showed lung metastases in 6 cases and soft tissue metastasis in one. ConclusionCCS 18F-FDG PET/CT image lacks specificity, but it can better demonstrate the extent and metastases of CCS, helping the accurate, timely, and more targeted therapy. |
