Chronic contained rupture of an abdominal aortic aneurysm presenting as a lower extremity neuropathy.

Rupture of an abdominal aortic aneurysm often presents with a pulsatile abdominal mass, abdominal pain, and hypotension. Recent clinical reports describe patients with less apparent clinical signs and symptoms who were found later in their evaluation to have a contained rupture of an abdominal aortic aneurysm. Even more unusual is a chronic contained rupture of an abdominal aortic aneurysm. Our patient had a chronic contained rupture of an abdominal aortic aneurysm that presented with erosion into the lumbar vertebral bodies and subsequent lumbar neuropathy. CT scan confirmed the contained rupture of the aortic aneurysm and the patient underwent successful repair of his aortic aneurysm. Our report discusses the significance of atypical presentations of abdominal aortic aneurysm rupture and the importance of prompt diagnosis and definitive repair.
