초록
폐동맥 육종은 극히 드문 질환으로 폐동맥 혈전증과 혼동되는 경우가 많다. 육종에서는 FDG 섭취가 증가되므로 18F-FDG-PET를 시행하면 FDG 섭취가 없는 색전증과 구별할 수 있지만 해상도가 떨어지는 단점이 있다. 그러므로 CT 영상을 접목한 PET/CT는 폐동맥 육종과 혈전증을 보다 선명하게 구별할 수 있다. 저자들은 혈전증과 감별이 어려운 폐동맥 병변에 대해 PET/CT로 폐동맥 육종의 진단에 도움을 받았던 증례를 경험하였기에 문헌고찰과 함께 보고하는 바이다.

Abstract
Primary pulmonary artery sarcoma is a rare malignant tumor arising from the pulmonary artery. Diagnosis of primary pulmonary artery sarcoma is quite difficult and the conditon is often misdiagnosed as a more common disease, such as a pulmonary embolism. PET can help in diagnosing a pulmonary artery sarcoma due to the increased uptake of 18F-FDG in the area of the tumor. However, the poor anatomic resolution of PET has limited its clinical applications in pulmonary vascular disease. The recently developed PET/CT is the fusion of PET and CT that improves the anatomical resolution of PET. We report a case of a primary pulmonary artery sarcoma mimicking a pulmonary embolism that was diagnosed with PET/CT and confirmed with a surgical resection. (Tuberc Respir Dis 2007; 62: 232-236)
