CTICasesAortic Valve Papillary Fibroelastoma
Imaging findings
Contrast-enhanced cardiac CT demonstrates a small, well-defined nodule attached to the aortic side of the aortic valve leaflet. The lesion is small, mobile, and sharply marginated.
Key takeaways
Papillary fibroelastomas are the most common benign tumors of the cardiac valves. While cardiac vegetations typically favor the ventricular side of the aortic valve, papillary fibroelastomas preferentially arise on the arterial/aortic side, which is a helpful anatomical rule of thumb for differentiation on high-resolution CT or echocardiography.
