Pulmonary valve sarcoma in patient with coronavirus disease of 2019 (COVID-19), mimicking pulmonary thromboembolism, a very rare case.

Pulmonary artery and pulmonary valve sarcoma are malignant and very rare vascular tumors with aggressive clinical course and very poor outcomes. Patients affected by coronavirus disease of 2019 (COVID-19) are at a higher risk for thromboembolism complication. We describe a young woman with a history of coronavirus pneumonia and progressive dyspnea, hemodynamic disturbance, edema with initial evaluation, and clinical diagnosis of pulmonary thromboembolism. But further imaging study and pathology demonstrated giant sarcoma of pulmonary valve, obstructing pulmonary valve and extending to right ventricular outflow tract and main of pulmonary artery.
