Lower Extremity Weakness and Back Pain from a Ruptured Iliac Artery Aneurysm: A Case Report

ABSTRACT

An isolated iliac artery aneurysm is a rare condition. Its prevalence is less than 0.01% of the general population and less than 1% of all vascular aneurysms. Metachronous occurrence of an iliac artery aneurysm is very rare, and its prevalence is unknown. Most iliac artery aneurysms do not have any clinical symptoms. If there are symptoms, they are due either to compression of adjacent organs, which depends on the anatomical position of the aneurysm, or to rupture. Aneurysmal rupture can present very variable clinical symptoms, which originate from the anatomical position, so diagnosis is often delayed. We report a case of a common iliac artery and an internal iliac artery aneurysm presenting as temporary lower extremity weakness and back pain, and we present a review of related literature.
