Proximal pseudoaneurysm coiled five days prior to imaging. Two new pseudoaneurysms have developed - one distal to the embolised pseudoaneurysm, and one proximal.
The patient previously had surgery to remove the right hepatic lobe for a hepatic adenoma. This may have led to ascending cholangitis, which predisposes the hepatic artery to multiple pseudoaneurysms via inflammation. The formation of multiple pseudoaneurysms indicates that the arterial walls were affected by cholangitis.
