Objective: To improve the differential diagnosis of pulmonary artery sarcoma from pulmonary embolism.
Method: Case analysis and literature review.
Results: Pulmonary artery sarcoma had similar clinical features as pulmonary thromboembolism. When the radiological features such as unilateral hilar enlargement and massive lumps in main trunk of pulmonary artery were observed and clinical deterioration occurred after thrombolytic and anticoagulant therapy, pulmonary artery sarcoma should be considered seriously in patients with suspected pulmonary thromboembolism.
Conclusion: Pulmonary artery Sarcoma can be easily misdiagnosed as pulmonary thromboembolism.
