Recurrent Pulmonary Intimal Sarcoma Involving the Right Ventricular Outflow Tract

Intimal sarcoma of the pulmonary artery is commonly misdiagnosed as chronic pulmonary embolism. Rarely, it can involve the right ventricular outflow tract and the pulmonary valve. We report a patient who was treated surgically for an intimal sarcoma of the pulmonary artery involving the right ventricular outflow tract and the pulmonary valve. The sarcoma recurred in about 8 weeks. It responded favorably to chemoradiation therapy and shows some signs of regression. (Ann Thorac Surg 2011;91:e41-2) (C) 2011 by The Society of Thoracic Surgeons
