Abstract

Background: The purpose of this case report is to describe a case of multiple intrahepatic artery aneurysms during treatment for IgG4-related sclerosing cholangitis (IgG4-SC) and to provide information for daily practice.

Case summary: A 64-year-old Japanese woman was diagnosed with IgG4-SC five years prior and was receiving maintenance treatment with prednisolone 7.5-10 mg/day. She developed abdominal pain and a sudden onset of black stool and was admitted to our hospital. Abdominal contrast-enhanced computed tomography (CT) and ultrasonography (US) revealed multiple intrahepatic artery aneurysms that developed during the treatment for IgG4-SC. Emergency transarterial embolization for multiple hepatic artery aneurysms was performed. Hepatic artery aneurysms disappeared on contrast-enhanced CT and US, the progression of anemia ceased, and the melena resolved. Thus, hemostasis was achieved.

Conclusion: Hepatic artery aneurysms should be considered poor prognostic complications of IgG4-SC.

igg4相关性硬化性胆管炎治疗中多发肝内动脉瘤1例

背景：本病例报告的目的是描述一例在治疗igg4相关性硬化性胆管炎（IgG4-SC）过程中出现的多发肝内动脉瘤，并为日常实践提供信息。病例总结：一名64岁的日本女性5年前被诊断为IgG4-SC，并接受强的松龙7.5-10 mg/天的维持治疗。她出现腹痛和突然出现黑便，并住进我院。腹部对比增强计算机断层扫描（CT）和超声检查（US）显示在治疗IgG4-SC期间出现多个肝内动脉瘤。急诊经动脉栓塞治疗多发肝动脉瘤。肝动脉动脉瘤在增强CT和US上消失，贫血停止进展，黑黑消失。从而止血。结论：肝动脉动脉瘤应视为IgG4-SC的不良预后并发症。
