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.
