摘　　要：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 ultra-sonography(US)revealed multiple intrahepatic artery aneurysms that developed during the treatment for IgG4-SC.Emergency transarterial embolization for mu-ltiple 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.
