We report the case of a 32-year-old male patient with symptoms of cerebrovascular accident manifesting with dysarthria. A transesophageal echocardiogram showed a floating mass localized in the ascending aorta, and a multislice computed tomography evaluation confirmed the diagnosis. With a comprehensive assessment of the mass, we decided on surgical intervention. A pedunculated and fragile mass was seen just near the right coronary ostium. The measured dimensions were 7.7 x 1.0 x 1.5 cm. The removed mass has been analyzed histopathologically and found to be the cause of the neurologic findings with an uncertain underlying etiology.References
