Atherosclerotic Aortic Aneurysm An unusual cause of Spastic Paraparesis

Abstract

Aortic aneurysm causing bone erosion is uncommon and is rarely associated with neurological deficits. Only few cases have been reported. We report a case of atherosclerotic aneurysm of the descending thoracic aorta causing extensive erosion of vertebral bodies T5-8, leading to invasion of the spinal canal and compression of the cord. The clinical signs were chronic thoracolumbar pain and spastic paraparesis. Clinicians must remain cognizant while evaluating a case of spastic paraparesis about the possibility of aortic aneurysm, a potentially treatable cause.
