Presentation
Acute on chronic lower back pain.
Patient Data
Large infra-renal abdominal aortic aneurysm, with variable signal within, in keeping with thrombus. This extends nearly to the aortic bifurcation.
Extensive destruction of the anterior aspect of the lumbar vertebra.
No para-spinal collection.
Gigantic infra-renal abdominal aortic aneurysm, with a large volume of contained thrombus. This displaces the kidneys laterally.
Dissection flap distal to the aneurysm sac.
Extensive bone scalloping and destruction of multiple lumbar vertebra, with bits of transverse process 'floating' in the aneurysm thrombus.
Case Discussion
This is the largest abdominal aortic aneurysm I have ever seen and with the most amazing bony destruction, especially in view of the aneurysm being non-inflammatory.
Quite breathtaking that the patient presented to an orthopedic ward and received an inpatient MRI lumbar spine to look for disc disease.
The patient underwent successful surgery, albeit the dissection flap extended and ruptured 'on table'.
