Severe erosion of lumbar vertebral body because of a chronic ruptured abdominal aortic aneurysm.

BACKGROUND CONTEXT: Erosion of vertebral bodies because of abdominal aortic aneurysm is an extremely rare condition. This vertebral destruction is usually seen after aortic graft surgery; nevertheless, it is not expected in primary aortic aneurysms.

PURPOSE: The purpose of this article was to present a patient who suffers from back and hip pain because of a chronic ruptured primary aortic aneurysm.

STUDY

DESIGN

Case report.

METHOD: A 51-year-old patient had complaints of back pain. Physical examination revealed a pulsatile mass in the periumblical region. By using conventional radiographies, vertebral erosion was detected at the anterior part of L3-L4-L5 vertebrae. A chronic ruptured thrombosed aortic aneurysm was identified by magnetic resonance imaging.

RESULTS

After resection of the aneurysm, it was possible that the lack of anterior column support could result in future instability. Therefore, an L4-L5 anterior partial corpectomy and reconstruction of the anterior defect with titanium mesh cage with posterior instrumentation and fusion were performed.

CONCLUSION

It was concluded that back pain caused by chronic aortic aneurysms is a rare condition and may be one of the possible etiologies in differential diagnosis of low back pain and/or sciatica in some patients.
