A rare primary pulmonary artery tumor caused lung infarcts and pulmonary hypertension in a 57-year-old man. Surgical resection led to a disease-free outcome, highlighting the importance of considering vascular tumors in diagnosing lung pathologies.

Area of Science:

  • Cardiovascular Medicine
  • Thoracic Surgery
  • Oncology

Background:

  • Primary tumors of the pulmonary artery are exceedingly rare, often presenting with nonspecific symptoms.
  • Pulmonary hypertension and pulmonary infarcts can be secondary manifestations of vascular obstruction.

Observation:

  • A 57-year-old male presented with cough, chest pain, and dyspnea.
  • Initial imaging revealed peripheral lung opacities, later confirmed as pulmonary infarcts.
  • Further investigation identified right pulmonary artery stricture and pulmonary hypertension.

Findings:

  • A hilar mass was resected, revealing a tumor within the pulmonary artery lumen causing near-total occlusion.
  • Histological examination confirmed a high-grade sarcoma with angiosarcomatous and osteosarcomatous components.

  • The patient showed clinical improvement with anticoagulant therapy and remained disease-free 9 months post-resection.

    • Implications:

    • This case underscores the diagnostic challenge of primary pulmonary artery sarcomas.
    • Early surgical intervention is crucial for potentially curative outcomes in resectable cases.
    • Highlights the need for comprehensive vascular imaging in patients with unexplained pulmonary hypertension and infarcts.
