肝门小胆管癌的多层CT分析

Multislice CT analysis for small hepatic hilar cholangiocarcinoma

目的:探讨肝门小胆管癌的多层CT影像表现和诊断价值。方法:收集13例经手术及病理证实的直径小于2cm的肝门胆管癌,回顾性分析其多层CT表现。结果:13例病灶CT:平扫均为等密度。增强扫描动脉期10例病灶呈中等强化,3例未见强化;门脉期13例病灶均表现为中等强化,其中见8例肿瘤邻近层面的胆管壁呈不规则的环形强化,其厚度均超过2mm。结论:多层CT对诊断肝门小胆管癌有很大价值。

Objective： To evaluate multislice CT appearances and diagnostic value of small hepatic hilar cholangiocarcioma. Methods： 13 cases of hepatic hilar cholangiocarcioma proved by surgically and pathologically were collected, the diameter of which is less than 2cm. Multislice CT manifestation were retrospectively analyzed.Results： The lesions of 13 cases displayed isodensity on plain CT scans. Showed enhancement on enhanced CT scans during arterial phase in 10 cases, showed no enhancement in 3 cases, and showed enhancemeat during portal phase in all cases, the common bile duct wall showed irregular ring-like enhancement in 8 cases, the thickness of which is over 2mm. Conclusion： Multislice CT is valuable in diagnosis of small hepatic hilar cholangiocarcinoma.
