儿童肝脏间叶性错构瘤CT表现

摘要

Objective To explore the CT manifestations of pediatric mesenechymal hamartoma of liver (MHL).Methods Clinical data of 15 cases with MHL confirmed by surgery and pathology were retrospectively analyzed.All children were performed with CT scans including plain and enhanced scans,and the imaging features were analyzed.Results All the lesions were solitary,and 9 masses located at the right lobe of liver,4 located at the left lobe,the others located at both right and left lobe.The maximum diameter of lesions was from 5 cm to 30 cm,with an average of (11.52±6.84) cm.Ten cases were cystic and solid mixed,5 cases were solid.After contrast administration,the solid component and the septa of the masses showed enhancement while no enhancement was observed in the cystic component.Two cases had the spot-like calcification.Conclusion MHL has some special characteristics in the CT scan before surgery,which should be differentiated from other cystic and solid tumors of live.Some MHLs can be diagnosed when combined with the clinical information and CT images.%目的 探讨儿童肝脏间叶性错构瘤的CT表现.方法 回顾性分析经手术病理证实的肝脏间叶性错构瘤15例患儿的临床资料,对患儿均行CT平扫及增强扫描,分析其影像学表现.结果 15例均为单发病灶,9例位于肝右叶,4例位于肝左叶,2例同时累及肝左、右叶.15例病灶的最大径为5～30 cm,平均(11.52±6.84)cm.CT表现为囊实混合型10例、实性型5例,增强后肿瘤实性部分及分隔强化,囊性部分无强化,2例病灶内出现斑点状钙化灶.结论 术前肝脏间叶性错构瘤的CT表现有一定的特征性,应注意与肝脏其他囊实性肿瘤相鉴别,结合临床和CT表现可做出正确诊断.
