title: Cardiac papillary fibroelastoma as a cause of embolic stroke: ultrasound and histopathological characteristics.
abstract: Although a cardiac papillary fibroelastoma is a benign cardiac tumor, it can cause severe embolic complications. A 51-year-old man presented with an ischemic stroke in the right middle cerebral artery territory. Transesophageal echocardiography revealed a small mobile tumor on the mitral valve as the only detectable source of emboli to the brain. On histology, the tumor was diagnosed as a papillary fibroelastoma. In this paper, the detailed characteristics of the tumor on ultrasound and histopathology are documented. In patients with cryptogenic stroke, transesophageal echocardiography should be done to rule out such an unusual emboligenic heart disease.
