title: Right outflow tract obstruction by a pedunculated neurofibroma: case report and literature review.
abstract: Right outflow tract obstruction due to neurofibroma is rare, with only four cases identified in the world literature. Obstruction due to a pedunculated neurofibroma has never been reported. A 36-year-old woman with no known heart disease presenting with dyspnea, palpitations and chest pain was shown on echocardiogram to have a mobile right ventricular mass. Cardiac catheterization revealed normal coronary arteries and right ventricular outflow tract obstruction by a pedunculated mass, which was surgically removed and histologically proven to be a benign neurofibroma. Following surgery the patient's symptoms disappeared, with no recurrence three years postoperatively.
