【摘要】：目的探讨肝脏上皮样血管平滑肌脂肪瘤(epithelioid angiomyolipoma,EAML)的CT表现,以提高对EAML的诊断水平。方法回顾性分析2010年3月至2016年6月经舟山市普陀区人民医院及温州医科大学附属慈溪医院诊治的5例经病理学证实的肝脏EAML患者的CT及临床资料,并复习有关文献。结果 5例均为单发,CT显示肿瘤位于肝右叶3例,左叶1例,尾状叶1例;4例类圆形,1例分叶状;大小4.9 cm×4.1 cm~15.1 cm×21.3 cm,界限均清楚。平扫呈不均匀低密度肿块,1例内见斑片状脂肪密度影。增强动脉期5例呈中度到明显强化,3例门静脉及延迟期持续强化呈相对较高密度,呈"快进慢出"强化模式,另2例强化程度降低呈较低密度,呈"快进快出"强化模式。3例强化不均匀,可见明显强化区域和无强化的坏死区以及畸形血管影混杂分布,其中1例另见无强化片状脂肪密度灶;2例强化较均匀,内部见少许纤细血管影分布。3例延迟期见轻度强化假包膜影。5例均经手术治疗,术后随访6~38个月,均未见复发转移。结论肝脏EAML的CT表现具有一定特征,CT对其诊断及鉴别有较大价值。
[Abstract]:Objective to investigate the CT manifestations of epithelioid angiomyolipoma (EAML) of the hepatic epithelioid angiomyolipoma (EAML) in order to improve the diagnostic level of EAML. Methods a retrospective analysis of 5 cases of liver EAML confirmed by pathology from March 2010 to 2016 in Zhoushan Putuo People's Hospital and Wenzhou Medical University, Wenzhou Medical University, was analyzed. CT and clinical data, and review the relevant literature. Results 5 cases were single, CT showed tumor in the right lobe of the liver in 3 cases, left lobe in 1 cases, caudate lobe in 1 cases, 4 cases of round, 1 case of lobulate; the size 4.9 cm * 4.1 cm~15.1 cm x 21.3 cm, the boundary was not uniform low density mass, 1 cases of plaque like fat density. Enhanced 5 cases of arterial phase in the middle Degree to obvious intensification, 3 cases of portal and delayed continuous intensification were relatively high density, showing "fast forward and slow out" intensification mode, the other 2 cases were lower density, and the intensification mode of "fast forward fast out" was not uniform, and.3 was enhanced inhomogeneous, obviously enhanced region and no strengthening necrotic area and malformed vascular mixed distribution, of which 1 cases were also seen. There was no enhanced flake fat density, 2 cases were more homogeneous, and a little thin blood vessel shadow was found in.3 cases..5 cases with mild fortified capsule shadow were treated by operation, and no recurrence and metastasis were observed for 6~38 months after operation. Conclusion the CT manifestations of liver EAML had certain characteristics. CT was of great value for the diagnosis and identification of the liver.
