Case Report


The patient was a 68-year-old woman with a history of multiple cerebral emboli. The patient presented with dysarthria, dysphagia, and left facial paralysis. Emergent MRI demonstrated multiple emboli in the brain stem and left occipital lobe. Echocardiography and chest CT demonstrated floating emboli entrapped in the foramen ovale and pulmonary emboli in both main pulmonary arteries. Emergent pulmonary embolectomy and extraction of the emboli on the foramen ovale were successfully performed without neurological exacerbation.
