Olfactory groove meningiomas (OGMs) are rare, intracranial tumors located in the anterior cranial fossa that grow along the nerves between the brain and the nose.
They arise from the region of the frontosphenoidal suture and may involve any part of the area from the crista galli to the planum sphenoidale 1) 2) 3).
