Acute thrombosis of an abdominal aortic aneurysm presenting as cauda equina syndrome.

Acute aortic occlusion is an uncommon vascular emergency that can present with predominantly neurologic symptoms owing to spinal cord ischemia. We describe a 62-year-old woman who experienced acute thrombosis of an abdominal aortic aneurysm that initially presented as cauda equina syndrome. She was treated operatively with an axillary bifemoral bypass. Our case report is followed by a discussion of acute aortic occlusion.
