Abdominal Aortic Aneurysm Presenting as Back Pain to a Chiropractic Clinic: A Case Report

A, An AP lumbar spine radiograph showed a curvilinear atherosclerotic (calcified) lateral wall of an abdominal aortic aneurysm just lateral and left of the L4 and L5 vertebral body (arrows). B, A lateral lumbar spine radiograph showed 7.0-cm fusiform aneurysmal dilation of the abdominal aorta anterior to the L4 and L5 vertebral body (arrowheads). C, Ferguson's view (AP tilt-up) of the lumbar spine showed bilateral sacular atherosclerotic dilation of the common iliac arteries (arrows). In addition, the 3-view lumbar spine series showed degenerative joint disease.

A, An axial ultrasound scan through the upper abdomen revealed a 5.94-cm aneurysmal dilation of the aorta with 3.37 cm of true lumen. B, An axial ultrasound scan through the pelvis revealed bilateral aneurysmal dilation of the common iliac artery.

A, An axial CT angiogram through the mid abdomen showed contrast filling in the true lumen of the aorta with atherosclerotic calcification of the peripheral aneurysmal wall. Thrombus surrounds the true lumen (arrows). B, An axial CT angiogram through the pelvis showed bilateral common iliac artery aneurysm with atherosclerotic calcification of the wall. C, A coronal reformatted CT angiogram showed a fusiform, infrarenal aortic aneurysm, which extended bilaterally into the common iliac artery. D, A volume-rendered 3D CT angiogram showed an infrarenal aortic and bilateral common iliac artery aneurysm.
