A transesophageal echocardiogram (TEE) revealed a 10 × 8 mm mass on the right coronary cusp of the aortic valve. Differential diagnosis included PFE versus thrombus. Following a neurology evaluation, the patient was anticoagulated and scheduled for urgent cardiac surgery. During surgery, an 8 × 7 mm mass was sharply excised from the right coronary leaflet's anterior surface. Further examination revealed additional masses: a 3 mm mass on the underside of the right coronary leaflet, a 2 mm mass on the non-coronary leaflet, and another 2 mm mass on its underside. All masses were excised, and pathology confirmed the diagnosis of PFE.
