原发性肝内周围型胆管细胞癌CT表现

目的：通过原发性肝内周围型胆管细胞癌CT表现，提高对原发性肝内周围型胆管细胞癌的认识。方法：回顾性分析经病理证实的42例原发性肝内周围型胆管细胞癌的CT表现。结果：CT平扫所有病理均为低密度灶。动态CT增强检查病灶多表现为不均匀轻度渐进性的向心性强化；其中26例出现大片无强化低密度区，病灶局部肝包膜可有回缩，23例病灶周围肝内胆管可有轻度扩张和结石。结论：原发，陛肝内周围型胆管细胞癌CT表现有一定的特征性。

Primary Intrahepatic Peripheral Cholangiocarcinoma:CT Findings

Objective： To analyse the CT findings of primary intrahepatic peripheral cholangiocareinoma （ PIHPCC ）, and to improve the understanding of primary intrahepatic peripheral cholangiocarcinoma. Method： CT appearances of primary intrahepatic peripheral cholangiocarcinoma proved by histologically in 42 cases were retrospectively analyzed. Result： The lesions appeared as single low density in all cases on plain CT scan, postcontrast CT scanning showed slightly in homogeneous enhancement in 42 patients, 26 patients showed unenhanced low density area with marginal enhancement,4 patients had delayed enhancement. Intrahepatic binary dilatation was found in 23 patients. Condusion： The CT - features of primary intrahepatie peripheral cholangiocarcinoma are of certain characteristic .
