Major cerebral infarction from tumor embolus.

Area of Science:

• Neurology
• Oncology
• Cardiovascular Medicine

Background:

• Metastatic synovial-cell sarcoma can affect the lungs.
• Lung resection is a treatment for advanced cancers.
• Cerebral infarcts can result from embolic events.

Observation:

• A 31-year-old man developed a right hemispheric infarct post-lung resection.
• The infarct occurred within 48 hours of surgery for metastatic synovial-cell sarcoma.
• Post-mortem examination revealed tumorous occlusion of the right internal carotid artery.

Findings:

• Cerebral tumor emboli can cause major strokes.
• This complication is associated with lung cancer surgery.
• Occlusion of the internal carotid artery by tumor emboli is a mechanism.

Implications:

• Consider stroke from tumor emboli in lung cancer patients post-pneumonectomy.
• Monitor for multi-organ or extremity ischemia symptoms.
• Early recognition is crucial for patient management and outcomes.
