Abstract
- Pulmonary artery sarcomas are rare, high-grade malignancies, primarily affecting the proximal elastic pulmonary artery and usually manifesting as tumoral impaction on imaging. Due to similar clinical and imaging findings, pulmonary artery sarcomas are frequently misdiagnosed as pulmonary thromboembolism or, occasionally, as vasculitis. Herein, we reported a case of pulmonary artery intimal sarcoma initially misdiagnosed as pulmonary thromboembolism and vasculitis due to its relatively atypical location and morphology, along with a literature review.
