Meningioma associated with subdural hematoma--case report.
The case of a 49-year-old female with a left parietal convexity meningioma associated with an acute subdural hematoma is described. She was admitted because of sudden onset of severe headache accompanied by nausea and vomiting. She was also confused, and 6 hours after admission she developed lethargy, right hemiplegia, and left mydriasis with no pupillary reaction to light. Computed tomography disclosed a round, extra-axial mass in the left parietal region; it was heterogeneously enhanced. Emergency craniotomy, performed after carotid angiography, revealed a tumor with a massive underlying subdural hematoma. The histological diagnosis was meningotheliomatous meningioma, and there were many meningothelial cells within the hematoma.
