目的：探讨肝脏黏液性囊性肿瘤的CT及MRI表现特征。方法：回顾性分析我院2011年1月—2016年6月5例经手术病理证实的肝脏黏液性囊性肿瘤的影像学表现，术前行320层多排螺旋CT和（或）1.5T MRI平扫及增强扫描、MRCP扫描。结果：5例肝脏黏液性囊性肿瘤均为良性，CT及MRI均表现为单发的类圆形多房囊性肿块，边缘光整，囊壁或分隔厚度较均匀，分隔可有钙化，增强扫描囊壁及分隔轻至中度延迟强化，肿瘤各分房内囊液密度和（或）信号不完全均匀，囊内均无实性成分或附壁结节，MRCP显示肿瘤均不与肝内胆管相通，周围结构受压改变。结论：肝脏黏液性囊性肿瘤的CT及MRI主要表现为多房囊性病变，囊壁薄且光整，增强后囊壁及其分隔有强化，病灶不与胆管相通，周围组织或结构受压改变，具有一定的特征性。
Abstract
Objective: To investigate the liver mucinous cystic neoplasm of CT, MRI image characteristics. Methods: Retrospective analysis of our hospital from January 2011 to June 2016, there were five cases confirmed by surgery of the liver mucinous cystic neoplasms, preoperative CT and(or) 1.5T MRI plain scan and enhanced scan, MRCP scan. Results: Five cases of liver cystic mucinous neoplasms were benign, CT and MR scan showed tumors were round single room separated more like cystic lesions, edge finishing, more uniform wall thickness or partition, the partition may have calcification, and the partition wall reinforcing mild to moderate enhancement, the sub-room tumor cyst fluid density or signal is not exactly the same, no capsule solid components or mural nodules, tumors and intrahepatic bile ducts are not the same, around structure under pressure to change. Conclusion: Hepatic mucinous cystic neoplasm in CT and MRI have a certain characteristic. The main appearance is multiple cystic lesions, thin and smooth wall, enhancement of cystic wall and septa, without connecting of bile duct, and compression of surrounding tissues and organs.
