title: A case of cardioembolic stroke due to intracardiac papillary fibroelastoma evaluated by using transesophageal echocardiography.
abstract: A 62-year-old woman had a prior ischemic stroke in the right temporal lobe with dysarthria and dysesthesia of the left hand. Embolic stroke of undetermined source (ESUS) was diagnosed and warfarin was administered. However, transient ischemic attack recurred upon admission to our hospital. Paroxysmal atrial fibrillation and cerebral arterial stenotic lesions were absent. Transesophageal echocardiography revealed a mobile hyperechoic structure on the aortic valve indicating papillary fibroelastoma. She was diagnosed with a brain embolism due to the intracardiac tumor which was surgically excised and pathologically confirmed as papillary fibroelastoma. This type of tumor is relatively rare but it is important as an embolic source especially in ESUS. Transesophageal echocardiography was indispensable for detecting the embolic source in this patient with ESUS.
