Core Tip
Core Tip: Hepatic artery pseudoaneurysm is a disease with poor prognosis due to high rupture and mortality rates. IgG4-related sclerosing cholangitis (IgG4-SC) is a disease caused by an autoimmune mechanism. we report a case of multiple ruptured intrahepatic artery pseudoaneurysms that occurred during the treatment of IgG4-SC. We consider the cause is complex: IgG4-related vasculitis, severe acute obstructive cholangitis and arteriosclerosis. Hepatic artery aneurysms should be considered poor prognostic complications of IgG4-SC.
