Abstract :
Olfactory groove meningiomas (OGMs) account for 4.5 to 13% of all intracranial meningiomas^1. Olfactory groove meningiomas arise in the midline over the cribriform plate and frontosphenoidal suture^1. It is well known that most of these tumors occupy the floor of the anterior cranial fossa, extending all the way from the crista galli to the tuberculum sellae^2. In case of large OGMs surgery represents a special challenge, because of their proximity to the arteries of the anterior circulation and the optic nerves. OGMs push the optic nerves and the chiasm downward and posteriorly as they grow.
