CTICasesAortic Root Abscess
Imaging findings
CT angiography shows a mechanical aortic valve prosthesis with paravalvular soft tissue thickening, phlegmon, and fluid-filled abscess cavities around the aortic root, particularly under the right coronary ostium. Blood cultures were negative.
Key takeaways
Aortic root abscess is a severe complication of infective endocarditis, particularly in patients with prosthetic heart valves. It represents a surgical emergency due to the risk of paravalvular leak, rupture, or conduction block. Diagnosis is confirmed on CT showing non-enhancing paravalvular fluid collections.
