Huge Pseudoaneurysm at the Aortic Bifurcation Misdiagnosed as a Mesenchymal Tumor: A Case Report

Abstract

Aortic pseudoaneurysms (PA) vary in size and may remain asymptomatic. PAs may be caused by vascular injury, such as trauma or surgery, or other non-traumatic causes, such as Bechet disease, infection, or penetrating atherosclerotic ulcers. The diagnosis of PAs may have been delayed for decades. We present a case of a PA detected incidentally in a male patient who experienced traumatic bowel perforation due to blunt abdominal trauma 30 years before presentation. Computed tomography (CT) displayed a 9.2 cm mass in the pelvis, initially considered a neoplasm of small bowel origin. Further analysis of the CT images suggested a thrombosed PA at the aortic bifurcation, which was confirmed via surgical exploration. Graft interposition was performed using a Dacron 16-8 mm graft and the patient recovered without any complications. This case highlights the importance of a high index of suspicion for the diagnosis of a thrombosed aortic PA.
