Magnetic resonance imaging of the lumbar spine. (a) T2-weighted image, sagittal. (b) T2-weighted image, axial. (c) T1 postcontrast, sagittal. (d) T1 postcontrast, axial. (e) computed tomography angiography of the chest, sagittal. The arrows depict the abrupt lack of contrast in the aorta, confirming acute aortic occlusion.

On second review, his lumbar spine MRI depicted signal change in the aorta concerning for a thrombus [Figure 1].
Three-dimensional aortic reconstructions. (a) Preoperative reconstruction demonstrating acute aortic occlusion. (b) Postoperative reconstruction after aortoiliac thrombectomy confirming aortic patency without residual thrombus. The arrow depicts an abrupt filling defect in the aorta confirming acute occlusion.

CT angiography findings showed an occlusion of the infrarenal abdominal aorta and bilateral common iliac arteries [Figure 2]. One week following presentation, angiography was performed and demonstrated resolution of the aortic thrombus, as shown in Figure 2b.
