Abstract

<p>Intimal sarcoma of the pulmonary artery is a rare disease associated with a poor prognosis. We report the case of a 64-year-old female who was admitted to our hospital with atypical genital bleeding caused by endometrial cancer. Computed tomography revealed deep vein thrombosis, right pulmonary artery thrombi, and a left pulmonary artery mass. Post hysterectomy, the insertion of an IVC filter and anticoagulant therapy were performed. Although the right pulmonary artery thrombi were diminished, the size of the left pulmonary artery mass increased gradually. Positron emission tomography-CT showed abnormal FDG uptake in the mass. Biopsy of the mass via cardiac catheterization indicated pulmonary artery intimal sarcoma. A left pneumonectomy with pulmonary aterioplasty was performed under cardiopulmonary bypass via median sternotomy. Pathological examination confirmed a diagnosis of intimal sarcoma of the pulmonary artery. Eight months after pneumonectomy, the tumor relapsed in the right lung. Nine months after the operation, she died of pneumonia.</p>
