AbstractCardiac papillary fibroelastoma is a benign and rare primary tumor of the heart that is most frequently located in the aortic or the mitral valves. Papillary fibroelastoma arising from the left atrium is exceedingly rare, comprising less than 7% of all cardiac papillary fibroelastomas. Tumors in this location could be a source of cardioembolic stroke, often in the anterior circulation of the cerebrum. A 66-year-old female presenting with right hemiparesis, central facial palsy, homonymous hemianopia, and dysarthria received intravenous thrombolysis for stroke without apparent improvement. Magnetic resonance imaging of the brain revealed ischemic infarction in the territories of the left middle and posterior cerebral arteries. A tumor with a maximal diameter of 2.3 cm was disclosed during workup for possible cardioembolic stroke with transthoracic echocardiography and computed tomography of the heart. The clinical course was complicated by stroke-in-evolution and hemorrhagic transformation. The patient underwent left atrial tumor excision and left atrium appendage closure. In-patient stroke rehabilitation programs were also initiated after the conditions stabilized. No clinically significant complications developed after the operation. Neurological functions improved and the patient was able to perform most basic daily living activities with some assistance. An exhaustive search for the cause of cardioembolic stroke is paramount, as management strategies may differ from patients with thrombotic stroke.
