title: Olfactory Groove Meningiomas: Acute Presentation and Potential : Pitfalls in Management and Functional Restoration.
abstract: Meningiomas are typically benign, slow-growing lesions that present after an insidious onset of symptoms related to mass effect. The acute presentation of a patient who has suffered a transtentorial herniation event due to a meningioma is rare. There are only few publications describing such a presentation in the absence of hemorrhage [1]. In this case report, a patient with an olfactory groove meningioma presenting with signs and symptoms of transtentorial herniation in the absence of tumor-associated hemorrhage is discussed. This is a unique presentation of such a lesion. The patient developed Anton's syndrome-binocular visual loss with blindness denial. Management considerations for patients with meningiomas that present with acute deterioration are discussed.
