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18 F-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。
Objective To investigate the PET / CT features of soft tissue clear cell sarcoma. Methods Ten cases of clear cell sarcoma confirmed by pathology were examined by 18F-FDG PET / CT preoperatively to analyze the imaging features and clinical features of the tumor. Results The mean normalized maximum uptake value (SUVmax) of primary lesions in 10 patients was 6.52 (ranged from 5 to 9.6). PET / CT found 7 cases of lung metastasis, 5 cases of soft tissue metastasis and 3 cases of regional lymph node metastasis. No bone, liver and brain metastasis were found. Six cases of lung metastasis and 1 case of soft tissue metastasis were found by CT / CT. Conclusion The 18 F-FDG PET / CT images of soft tissue clear cell sarcoma are not specific, but they can better show the extent and metastasis of the lesion, make the staging more accurate and timely, and help to choose the targeted treatment plan.
