[目的]探讨儿童肝脏间叶性错构瘤（M HL ）的CT影像学和病理学特征。[方法]回顾性分析6例M HL患儿的临床资料，分析CT特征，并与术后病理结果对照。[结果]所有患儿均为巨大单发病灶，其中5例位于肝右叶，1例位于肝左叶，平均最大径7．3（4．9～16．9）cm ；6例C T 平扫均表现为肝内巨大囊实性肿块，囊腔内可见分隔，增强扫描病灶实性部分及分隔强化，囊性部分无强化，病理结果显示肿瘤由富于血管的成熟的结缔组织所组成。[结论]M HL是一种少见的肝脏间叶性良性肿瘤，CT 表现与其病理组织学有一定特征性，结合临床特征有助于与肝脏其他肿瘤鉴别。

[Objective]To explore the CT imaging features of mesenchymal hamartoma liver (M HL ) in children .[Methods]Clinical data of 6 pediatric patients with M HL were analyzed retrospectively .CT features were analyzed and compared with postoperative pathological results .[Results]All patients were large single le-sion .Among them ,the lesions of 5 patients located in right lobe of liver ,and those of 1 patient located in left liver lobe .The average maximum diameter was 7 .3cm(4 .9~16 .9cm) .CT plain scan of 6 patients showed large solid and cystic lesion in liver and the separation in capsular space .The enhancement scan showed solid component and separation intensification .No intensification was found in cystic component .The pathological results showed the tumor was composed of rich blood vessels and mature connective tissue .[Conclusion]MHL is a benign liver tumor rarely seen .The CT findings and pathohistology have a certain characteristics . CT findings and pathohistology combined with clinical features are helpful to distinguish from other liver tumors .
