Chronic contained rupture of an abdominal aortic aneurysm is a rare but important differential diagnosis for longstanding back pain.
Consider chronic contained AAA rupture in recurrent low back pain with deficits; case report supports inclusion in differentials but leaves open prevalence and screening.
Abdominal aortic aneurysm (AAA) is one of the important differential diagnoses of back pain which is often missed. Chronic contained rupture is a rare event that can cause diagnostic difficulties, presenting in different ways such as back pain, neuropathy or groin mass. We are presenting a case of 46-year-old man who presented with history of recurrent low back pain radiating to his left leg, associated with sensory deficit in the left thigh. His complaint proved to be resulting from chronic contained AAA leak.
