目的探讨周围型肝内胆管细胞癌CT表现特征,提高CT诊断准确率。方法回顾性分析13例周围型肝内胆管细胞癌CT平扫和增强表现。结果 CT平扫13例均为类圆形或不规则形低密度灶,边界不清,病灶周围或病灶内均可见胆管扩张,CT增强扫描表现为特征性的从周边到中心的向心性强化,延迟强化,病灶周围肝内胆管轻度扩张,局部肝包膜回缩征象。结论 CT是周围型肝内胆管细胞癌的重要检查方法,病灶周围或病灶内胆管扩张和病灶延迟强化是周围型肝内胆管细胞癌的重要征象。
Objective To investigate the CT features of peripheral intrahepatic cholangiocarcinoma and to improve the diagnostic accuracy of CT. Methods Retrospective analysis of 13 cases of intrahepatic cholangiocarcinoma CT scan and enhanced performance. Results CT scan of 13 cases were all round or irregular low-density lesions, the border is unclear, lesions can be seen around the lesions or bile duct dilatation, CT enhanced scan showed a characteristic from the periphery to the central concentric enhancement, Delayed enhancement, mild intrahepatic bile duct dilatation around the lesion, local hepatic capsule retraction signs. Conclusion CT is an important method for the diagnosis of peripheral intrahepatic cholangiocarcinoma. Dilatation of the bile duct around the lesion or focal lesion and delayed focal enhancement are important signs of peripheral intrahepatic cholangiocarcinoma.
