中文摘要:
      目的 观察肝肾血管周上皮样细胞瘤(PEComa)CT表现。方法 回顾性分析经手术病理证实的18例肝PEComa及5例肾PEComa,观察其术前CT表现。结果 23例均为单发病灶,主要CT表现包括低/稍低密度(23/23,100%)、形态不规则(16/23,69.57%)、边界清晰(17/23,73.91%)、无包膜(21/23,91.30%)及增强后强化(21/23,91.30%)。18例肝PEComa中,13例密度均匀(13/18,72.22%),5例(5/18,27.78%)密度不均匀且见脂肪成分(5/5,100%)及血管增粗(4/5,80.00%)、少见出血坏死(1/5,20.00%)及钙化(0/5,0),增强后多表现为快进快出(16/18,88.89%)。5例肾PEcoma均呈不均匀密度、内见脂肪成分(5/5,100%),少见出血坏死(1/5,20.00%)、血管进入(1/5,20.00%)及钙化(0/5,0);增强后可呈快进快出(2/5,40.00%)、渐进性强化(1/5,20.00%)或无强化(2/5,40.00%)。结论 肝肾PEComa CT表现具有一定特征性。
英文摘要:
      Objective To explore CT manifestations of perivascular epithelioid cell tumor (PEComa) of liver and kidney. Methods Totally 18 hepatic PEComa and 5 renal PEComa confirmed by surgical pathology were retrospectively enrolled, and the preoperative CT manifestations were explored. Results Single lesion of liver or kidney was found in all 23 cases, and the main CT manifestations included low or slightly low density lesion(23/23, 100%), with irregular morphology (16/23, 69.57%), clear boundaries (17/23, 73.91%), non-envelope (21/23, 91.30%) and enhancement after administration of contrast agents (21/23, 91.30%). Among 18 cases of liver PEComa, most lesions (13/18, 72.22%) presented as uniform density, while some (5/18,27.88%) presented as non-uniform density lesions often contained with fat components (5/5, 100%) and thickened blood vessels (4/5, 80.00%) but rare hemorrhagic necrosis (1/5, 20.00%) nor calcification (0/5, 0). Fast in and fast out of contrast agents were observed in 16 (16/18, 88.89%) lesions. Uneven density and internal fat components were found in all 5 (5/5, 100%) renal PEComa, which rarely with hemorrhagic necrosis (1/5, 20.00%), blood vessels orientation (1/5, 20.00%) and calcification (0/5, 0). After enhancement, fast in and fast out, progressive enhancement and non-enhancement was observed in 2 (2/5, 40.00%), 1 (1/5, 20.00%) and 2 (2/5, 40.00%) cases, respectively. Conclusion CT manifestations of PEComa in liver and kidney had certain characteristics.
