Frontal Parafalcine Meningioma Presenting as Anterior Cerebral Artery Stroke

A 54-year-old woman presented with right grade 1 hemiparesis and aphasia (NIH Stroke Scale score 13) after 5 hours of initial symptoms. MRI revealed an ischemic area in left anterior cerebral artery territory and a left frontal tumor (figure 1). Endovascular reperfusion was unavailable. Etiologic investigation, which included ECG, echocardiogram, routine blood analysis, renal and thyroid function, lipidogram, HIV, hepatitis and syphilis antibodies, thrombophilia markers, MRI, and cerebral angiography (figure 2), did not reveal another alteration than the mechanical compression of the artery. After 2 weeks of clinical investigation and stabilization, complete surgical resection was performed. Language symptoms improved and the patient remains in rehabilitation. Exceptionally, meningiomas can compress major cerebral arteries, resulting in transient neurologic symptoms.1 Even more rarely, they can present as a stroke, with an estimated incidence of 0.19%.2
