To report a rare case of recurrent cerebral embolism caused by direct cardiac invasion by lung adenocarcinoma.
Approach:
Case Description: A 41-year-old woman presented with acute right-sided hemiparesis and aphasia, diagnosed with left middle cerebral artery occlusion and treated with mechanical thrombectomy. A second embolic stroke occurred four days later, leading to further investigation reve…
Key Findings:
The patient experienced two embolic strokes within a week, both resolved via thrombectomy.
Imaging revealed a right lung adenocarcinoma infiltrating the pericardium, pulmonary vein, and left atrium.
No further embolic events occurred during follow-up after chemotherapy and anticoagulation.
Interpretation:
This case highlights the importance of considering tumor-related stroke in younger patients without traditional risk factors.
Limitations:
The case is based on a single patient, limiting generalizability.
Further investigations were declined by the patient post-discharge.
Conclusion:
This case illustrates a rare cause of recurrent cerebral embolism due to direct cardiac invasion by lung adenocarcinoma.
