title: Major intratumoral hemorrhage of a petroclival atypical meningioma: case report and review of literature.
abstract: Spontaneous intratumoral hemorrhage associated with a meningioma is an extremely rare event and has a very high rate of morbidity and mortality. We report a patient with a history of subtotal resection of a petroclival meningioma followed by gamma knife radiosurgery who presented with sudden neurological deterioration following intratumoral hemorrhage after 4 asymptomatic years. The patient underwent early resection of this atypical meningioma and evacuation of hematoma via a retrosigmoid transpetrosal approach and had rapid neurological improvement.
