Chronic contained abdominal aortic aneurysm rupture causing vertebral erosion.

Erosion of vertebral bodies by an abdominal aortic aneurysm is extremely rare. Chronic contained rupture can cause difficulties in diagnosis because there are many clinical presentations: back pain, sciatic pain, or an expansive abdominal mass. Computed tomography is the gold-standard diagnostic tool. We report the case of a 49-year-old man who suffered from back pain because of a chronic ruptured aortic aneurysm.
