Intrahepatic cholangiocarcinoma (ICC) is a relatively rare subtype of cholangiocarcinoma, and there has been an increasing incidence of ICC in Western countries in recent years. Surgical resection is the most effective treatment for ICC. However, overall outcomes are extremely poor given that most patients are diagnosed at an advanced stage, and postoperative ICC recurrence is still very high despite hepatic resection. We report a case of metastatic ICC to the stomach presenting after resection of the original tumor, with imaging characteristics highly resembling gastrointestinal stromal tumor (GIST) on imaging. Reported cases of metastatic ICC to the liver are sparse. Given that there is a significant difference in the survival rate between metastatic cholangiocarcinoma and other tumors arising from the gastrointestinal tract, including GISTs, it is important to delineate the differences via imaging features. We further discuss the imaging characteristics of intrahepatic ICC, comparing and contrasting it to other gastric tumors.
肝内胆管癌（ICC）是胆管癌中一种相对罕见的亚型，近年来西方国家ICC的发病率呈上升趋势。手术切除是ICC最有效的治疗方法。然而，由于大多数患者在晚期才被诊断出来，总体治疗效果极差，尽管进行了肝切除，术后ICC复发率仍然很高。我们报告了一例在原发肿瘤切除后出现胃转移的ICC病例，其影像学特征在成像上与胃肠道间质瘤（GIST）高度相似。报道的肝转移ICC病例较少。鉴于转移性胆管癌与包括GIST在内的其他胃肠道肿瘤的生存率存在显著差异，通过影像学特征来区分这些差异很重要。我们进一步讨论肝内ICC的影像学特征，并将其与其他胃部肿瘤进行比较和对比。
