Interhemispheric Acute Subdural Hematoma Secondary to Falx Meningioma: A Case Report.

This report describes an unusual case of falx meningioma associated with acute subdural hematoma, which is a rare presentation. A 76-year-old woman presented with right-sided hemiparesis and a known falx meningioma that had rapidly increased in volume over the previous year. Computed tomography revealed interhemispheric and left-hemispheric acute subdural hematomas. Preoperative embolization and surgical tumor removal were performed to improve the symptoms, and pathological examination of the tumor revealed transitional meningioma (WHO Grade I). The patient's paresis symptoms improved postoperatively. This report provides valuable insights into the management and outcomes of falx meningioma with acute subdural hematoma, suggesting aggressive surgery to improve postoperative recovery.
