Pulmonary artery sarcoma mimicking massive pulmonary embolus: a case report

Area of Science:

• Cardiovascular Surgery
• Surgical Oncology
• Pulmonary Hypertension

Background:

• Intimal sarcomas of the pulmonary artery are rare and challenging to diagnose, often mimicking pulmonary thromboembolic disease.
• Early and accurate diagnosis is crucial for effective treatment and improved patient outcomes.

Observation:

• A patient presented with symptoms suggestive of massive pulmonary embolism, including right ventricular outflow tract obstruction.
• Diagnostic imaging revealed a primary pulmonary artery sarcoma.

Findings:

• The patient underwent successful surgical intervention, including pulmonary artery thromboendarterectomy.
• Pulmonary valve replacement and tricuspid valve annuloplasty were also performed as part of the treatment.
• This multi-faceted surgical approach addressed both the tumor and the resulting hemodynamic compromise.

Implications:

• This case demonstrates the feasibility of aggressive surgical management for primary pulmonary artery sarcoma.
• Successful surgical outcomes can be achieved even in complex presentations involving significant obstruction.
• Highlights the importance of considering rare tumors in the differential diagnosis of pulmonary vascular diseases.
