摘　　要：目的：探讨小儿肝间叶性错构瘤的CT表现,提高对该病的诊断水平。方法：回顾性分析12例经手术病理证实的肝间叶性错构瘤患儿的CT资料,12例均行CT平扫及增强扫描。结果：12例中病灶位于肝右叶4例,位于肝左叶2例,同时累及肝左、右叶6例。瘤体直径7~17 cm,平均12.5 cm。CT表现取决于肿瘤囊实性成分比例和分布,表现为囊性型（2例）、囊实混合型（9例）和实性型（1例）,增强后肿瘤实性部分及分隔强化,囊性部分无强化,1例病灶内见点状钙化。结论：肝间叶性错构瘤的CT表现有一定特征性,结合临床特征并注意与肝脏其他囊实性肿瘤鉴别,术前大多能做出正确诊断。Objective：To study the CT features of mesenchymal hamartoma of liver（MHL） and to improve the level of CT diagnosis.Methods：The CT materials of 12 cases（5 boys,7 girls） with surgery and pathology proved MHL were retrospectively analyzed.All of the 12 cases underwent spiral CT scanning and contrast enhancement scanning.Results：4 masses located at the right lobe of the liver,2 located at the left lobe,the other located in both right and left lobe.The tumor size ranged from 7 to 17cm（mean 12.5cm） in diameter.There was correlation between the CT findings of MHL and the proportion and distribution of cystic or solid component in the masses.The masses were single cystic（n=2）,cystic-solid mixed（n=9） and solid（n=1）.After contrast administration,the solid component and the septa of the mass showed enhancement while no enhancement was assessed in the cystic component.Calcification was seen inside the tumor in one case.Conclusion：MHL display special CT characters and easy to distinguish it from other cystic solid mixed hepatic tumors under the help of patient＇s clinical symptoms before surgery.
