Loading images...
Axial non-contrast
The aorta and its branches show wall calcifications due to atherosclerotic disease. An infrarenal abdominal aortic aneurysm is demonstrated. The left posterolateral wall of the aneurysm extends into the left paralumbar region and follows the contour of the lumbar vertebrae with a draping effect ("draped aorta sign"). This is highly indicative of contained rupture.
Other findings:
- mesenteric, retroperitoneal, and pelvic fat stranding
- small hepatic cysts
- left renal cyst
- degenerative osseous changes
- subcutaneous edema
- cardiomegaly
- right pleural effusion
