报告８例经手术及病理证实的胆管细胞型肝癌，主要观察其ＣＴ、ＭＲＩ及血管造影表现。８例中男６例，女２例，年龄４２～６４岁（平均５２岁）。影像学检查包括ＣＴ（８例）、ＭＲＩ（７例）及血管造影（６例），主要表现：（１）ＣＴ平扫为单发分叶状低密度块影，巨块型者密度不均；注射造影剂后４例呈边缘性增强（４／６）；１例伴有肝硬化、脾大。（２）ＭＲＩＴ＿１加权像上病变呈低信号，Ｔ＿２加权像上信号较高，５例可见搬痕结构（５／７）；注射造影剂后早期，５例呈中等度边缘型强化（５／６），延迟像中心区信号不均；肝静脉及门静脉未见受侵征象。（３）血管造影表现为供血动脉增粗，被肿瘤包埋，显示僵直、拉长，４例末梢分支呈羽毛状。综合上述表现，下列征象可提示胆管细胞型肝癌：单发分叶状肿块，内有瘢痕结构；注射造影剂后呈轻～中等度边缘性增强；血管造影显示供血动脉增粗、包埋；合并肝静脉、门静脉侵犯及肝硬化少见。
Reported 8 cases of cholangiocarcinoma confirmed by surgery and pathology, mainly to observe the CT, MRI and angiographic performance. In 8 cases, there were 6 males and 2 females, aged 42-64 years (average 52 years old). Imaging examination included CT (8 cases), MRI (7 cases), and angiography (6 cases). The main manifestations were: (1) CT plain scan was a single lobulated low-density block shadow, and the density of giant block type was uneven. After injection of contrast agent, 4 cases showed marginal enhancement (4/6); 1 case had cirrhosis and splenomegaly. (2) MRIT_1 weighted images showed low signal on lesions, T_2 weighted images showed higher signal, 5 showed visible trace structure (5/7), and 5 patients had moderate marginal enhancement (5/6) early after injection of contrast medium. ), delayed signal like the central area is uneven; no hepatic vein and portal vein invasion signs. (3) Angiography showed a thickening of the feeding arteries, which was embedded by the tumor and showed rigidity and elongation. The peripheral branches of the 4 cases were feather-like. Taken together, the following signs may suggest bile duct cell type liver cancer: single lobulated mass with scarring structure; mild to moderate marginal enhancement after injection of contrast agent; angiography showing thickening and embedding of blood supply artery; merger Hepatic veins, portal vein invasion and cirrhosis are rare.
