摘　　要：目的 分析并总结小儿肝脏间叶性错构瘤（MHL）的CT表现特点，提高该病的诊断正确率。方法 回顾性分析经病理证实的5例MHL患儿的临床资料，所有病例术前均行全腹部平扫加增强扫描。结果 5例MHL患儿病变均位于肝右叶，瘤体长径约98~139 mm,平均最大径122 mm。4例患儿CT平扫表现为囊实性肿块，1例表现为实性成分为主。增强扫描实性部分及分隔强化，囊性部分无强化。5例病灶内均未见钙化。结论 MHL CT表现具有一定的特征，结合影像学特点及临床表现有助于与肝周及肝内其他常见肿瘤的鉴别。Objective To improve the diagnostic accuracy of pediatric mesenchymal hamartoma of liver （MHL） by analyzing and summarizing the CT findings. Methods Five pediatric patients with MHL confirmed by postoperative pathology were enrolled,all patients underwent contrast-enhanced CT before operation. Results All lesions were located in the right lobe of liver. The tumor size ranged from 98 mm to 139 mm （mean size was 122 mm）in diameter. Four cases showed cystic and solid mixed masses, and one solid masses. After contrast administration, the substantial part of the mass and its septa showed enhancement while no enhancement was observed in the cystic part. No calcification was observed in the tumor.Conclusion MHL has some special CT characters. Most of MHL can be diagnosed combined with clinical practice as well as CT.
