Abstract

Extensive remodeling of the anterior aspect of the lumbar spine was observed in two patients with a ruptured aneurysm of the abdominal aorta. Both patients survived as the rupture was contained in the first case and involved a false anastomotic aneurysm in the second. The patients presented with a clinical picture compatible with advanced stage cancer and a radiologic aspect showing anterior erosion of the vertebral bodies, suggestive of very advanced spondylodiscitis. The diagnosis was made on the basis of ultrasound and CT-scan evidence. There was no parallel relationship between the size of the ectasia and the spinal remodelling. A hypothetical pathogenic mechanism involving the intermittent pulsation of the aneurysm and ischaemia of the vertebral bone is proposed.

Aortic Aneurysm

An aortic aneurysm is the weakening and bulging of the blood vessel wall in the aorta. This causes dilatation of the aorta, which is usually asymptomatic but carries the risk of rupture and hemorrhage. Find the latest research on aortic aneurysms here.
