CTICasesCoral Reef Aorta
Imaging findings
CT angiogram of the abdomen demonstrates severe, exophytic, and heavily calcified atherosclerotic plaque projecting into the lumen of the abdominal aorta, resembling coral formations. The calcifications cause significant narrowing of the aortic lumen.
Key takeaways
Coral reef aorta is a rare and extreme form of atherosclerosis characterized by massive, exophytic, calcified plaques that grow into the aortic lumen. It typically occurs in the visceral and infrarenal segments of the abdominal aorta and can lead to severe renovascular hypertension, lower extremity claudication, or visceral ischemia.
