Pulmonary Artery Sarcoma Diagnosed Using an Endovascular Catheter Forceps Biopsy

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 ant...

Description
Summary: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. 18F-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.
