A Rare Case of Pulmonary Metastasis From Intracranial Grade 2 Meningioma

Meningiomas are the most common benign central nervous system tumors in adults. Meningiomas are typically categorized into three grades that reflect their aggressiveness, recurrence risk, and clinical prognosis. Although these tumors have low metastatic potential, the prognosis is significantly worse when metastases occur. Due to the scarcity of available literature on metastasis, the exact cause and treatment of metastatic disease are poorly understood. We present a rare case of a 62-year-old male with atypical meningioma with early pulmonary metastasis shortly after standard-of-care treatment, highlighting the importance of vigilant imaging surveillance in high-risk disease.
