Abstract

Hepatic artery aneurysms have an estimated incidence of approximately 0.002%, of which one half are pseudoaneurysms (PsAs). These typically occur following trauma or liver transplant and are often asymptomatic. An uncommon pathology, mycotic aneurysms or PsAs are those that result as a consequence of infections. The danger in mycotic processes stems from their complications of systemic seeding of infection, rupture, and possible exsanguination. This case reports a mycotic PsA that was found in an accessory left hepatic artery (aLHA) branching from the left gastric artery (LGA). The patient presented with recurrent Clostridium difficile colitis with perforation and was later found to have a left upper quadrant vascular lesion during repeat imaging after failing to progress in their clinical course. After multidisciplinary meetings with vascular surgery and interventional radiology, the patient eventually underwent endovascular coil embolization. This is the first documented case of a mycotic PsA secondary to recurrent C. difficile colitis located in an aLHA branching from the LGA.
