Abstract

We herein report a case of pulmonary artery sarcoma (PAS) in a 64-year-old woman. She was admitted to our hospital because of massive genital bleeding from endometrial cancer. Contrast-enhanced computed tomography (CT) revealed a left pulmonary artery mass and deep vein thrombosis. She underwent anticoagulant therapy for one year. However, the mass lesion gradually expanded. F-Fluorodeoxyglucose (FDG) positron emission tomography (PET)/CT showed a positive uptake of FDG by the mass. An endovascular catheter biopsy was performed for the differentiation of endometrial cancer metastasis or primary sarcoma. The biopsy specimen tissue comprised spindle-shaped cells. Thus, the patient was diagnosed with PAS.

摘要

我们在此报告一例 64 岁女性肺动脉肉瘤（PAS）病例。因子宫内膜癌引起大量生殖器出血，她被收入我院。增强 CT 显示左肺动脉肿块和深静脉血栓形成。她接受了一年的抗凝治疗。然而，肿块逐渐增大。氟代脱氧葡萄糖（FDG）正电子发射断层扫描（PET）/CT 显示肿块摄取 FDG 呈阳性。为了区分子宫内膜癌转移或原发性肉瘤，进行了血管内导管活检。活检标本组织由梭形细胞组成。因此，该患者被诊断为 PAS。
