Cardiac hemangiopericytoma growing in the left atrium.
A 49-year-old woman was seen because of exertional dyspnea. Two-dimensional echocardiography revealed the presence of a large mass in the left atrium. An urgent operation was performed because the tumor suddenly stuck in the mitral orifice. The lesion, which occupied the entire left atrium, was resected during cardiopulmonary bypass. Histologic analysis revealed malignant hemangiopericytoma.
