目的探讨肝血管平滑肌脂肪瘤(AML)的MRI与CT影像表现.方法对2009-2011年我院手术病理证实的12例肝AML临床资料进行回顾性分析.结果男3例,女9例,发病年龄34～60岁(平均44.17岁).12例共14个病灶,其中发生在肝左叶8个,右叶6个.9例行MRI检查,2例行CT检查,1例同时行CT及MRI检查.8个病灶边界较清晰；8个病灶于MRI和(或)CT上显示出脂肪成分；增强后门脉期至延迟期9个病灶强化程度稍减退或呈高信号；5例见肿瘤压迫周围血管包括门脉及腔静脉,1例左肝静脉早显,6例显示出扭曲畸形的血管.所有病灶均无门静脉癌栓.12例均手术切除并经病理证实为血管平滑肌脂肪瘤.结论影像学检查显示肝内肿瘤具有良好的边界、瘤内脂肪成分、增强延迟强化及扭曲畸形的血管时应考虑肝血管平滑肌脂肪瘤的可能.

Objective To investigate the magnetic resonance imaging (MRI) and computerized tomography (CT) imaging findings of hepatic angiomyolipoma (AML).Methods Twelve cases of hepatic AML,which were confirmed by pathologists between 2009 and 2011 in our hospital,were retrospectively analyzed.Results There were 3 males and 9 females with an average age of 44.17 years (range,34 to 60 years).There were 14 lesions,8 in left lobe,6 in right lobe.All of 12 cases were confirmed as angiomyolipoma by pathologists.Nine cases were performed with MRI,2 with CT,and 1 with both CT and MRI.The border of lesions were clear in 8 cases.Fat contents were shown on CT and/or MRI in 8 cases.After administrated with contrast medium,the lesion enhancement was still apparent or slightly decreased in 9 lesions from portal phase to delayed phase.The suppression of portal vein and inferior vena cava by tumor were seen in 5 lesions.Abnormal vascular distortion was seen in 6 lesions.None of 12 lesions were found with portal vein thrombosis.Conclusion The diagnosis of hepatic angiomyolipoma should be considered when CT and MRI show good boundaries,intratumoral fat content,delayed lesion enhancement,and vascular distortion.
