Abstract

Jesse J Jung, Floyd A Warren, Ronit KahanowiczDepartment of Ophthalmology, New York University School of Medicine, New York, NY, USAAbstract: Olfactory groove meningiomas can present as large and insidious masses in the anterior cranial base. Due to their location and minimal clinical symptoms, these tumors can go undetected until they have grown extremely large. We present a clinical case and discuss the surgical management of a 63-year-old man who presented for an initial eye examination with bilateral visual loss for over 2 years due to a giant olfactory meningioma encompassing his entire frontal lobe and compressing on his optic nerves.Keywords: olfactory groove meningioma, anterior skull base, optic atrophy, bilateral visual loss
