Key result
Advanced imaging techniques, including cardiac magnetic resonance and PET-CT, successfully identified pulmonary artery sarcoma in a patient with refractory pulmonary embolism-like symptoms.
Why the study?
Pulmonary artery sarcoma is a rare, aggressive malignancy often misdiagnosed as pulmonary embolism due to similar clinical presentations.
Case Report (n=1)
Pulmonary artery sarcoma should be considered in patients with PE-like symptoms refractory to standard anticoagulation therapy, and advanced imaging can aid in diagnosis.
Consider PAS with advanced imaging in anticoagulation-refractory PE now; leaves open protocolized pathways for this rare mimic.
Pulmonary artery sarcoma (PAS) is a rare but aggressive malignancy often misdiagnosed as pulmonary embolism (PE) due to similar clinical presentations. This case report presents an early 40s female with progressive dyspnea, hemoptysis, high pulmonary arterial pressures (112 mmHg), and right heart strain unresponsive to anticoagulation therapy. Imaging findings, including cardiac magnetic resonance and positron emission tomography-computed tomography, ultimately revealed PAS. This case highlights the importance of considering rare etiologies, such as PAS, in patients with PE-like symptoms refractory to standard treatment. Early detection using advanced imaging techniques can improve diagnostic accuracy and outcomes in this rare malignancy.

Luo et al. (2025) conducted a case report in Pulmonary artery sarcoma (n=1). Advanced imaging techniques (cardiac MRI and PET-CT) was evaluated on Diagnosis of pulmonary artery sarcoma. Advanced imaging techniques, including cardiac magnetic resonance and PET-CT, successfully identified pulmonary artery sarcoma in a patient with refractory pulmonary embolism-like symptoms.
