Anterior skull base meningiomas
- Olfactory Groove Meningiomas (OGM)
Nomenclature of anterior skull base meningiomas - Planum Sphenoidale Meningiomas
- Tuberculum Sellae Meningioma (TSM)
Comparison of OGM and TSM
| Factor | OGM | TSM |
|---|---|---|
| Location | Cribriform, frontosphenoid suture | Planum sphenoidale, tuberculum sellae |
| Blood supply | Ant & pos ethmoidals, middle meningeal, ophthalmic (meningeal branch, ACA & ACoA) | Pos ethmoidal (ACA & ACoA) |
| Olfactory nerves | Superolat | Inferolat |
| Optic nerve/chiasm | Inferolat | Superolat |
| ACA | Pos. to posterosuperior | Posterosuperior |
