目的 探讨混合型肝癌的临床病 理特点及增强CT表现。方法 回顾性分析 19例经手术病理证实的混合型肝癌的临 床病理特点及增强CT表现。结果 男性 14例，女5例，平均年龄64.2岁(27-74 岁)。CT增强扫描表现为 4种不同的强 化方式：I型为快进快出型强化(5例)； II型为渐进型强化(7例)；III型为不均 匀持续型强化(3例)；IV型为此起彼伏 型强化(4例)。肝门部淋巴结转移7例 (36.84%)。结论 混合型肝癌老年男性多 见，以肝门部淋巴结为主要转移途径。 不均匀持续型及此起彼伏型的CT强化方 式有助于提示诊断。

Objective To explore the clinico-pathological and contrast enhanced CT characteristics of combined hepatocellular-cholangiocarcinoma (CHC). Methods The clinico-pathological and contrast enhanced CT characteristics of CHC in 19 cases confirmed by postoperative pathology, were analyzed retrospectively. Results There were14 men and 5 women with a mean age of 64.2 years (range 27-74). The characteristics of contrast enhanced CT could be summarized to 4 different kinds of enhancement patterns: type I as wash in and wash out (5 cases), Type II as gradual enhancement (7 cases), Type III as inhomogeneous sustained enhancement (3 cases), Type IV as one falls another rises (4 cases). Conclusion CHCs mainly affected old men, with some cases showing characteristic CT enhancement patterns.
