Orbital meningiomas

Meningiomas of the orbit are uncommon. They can be divided into two broad categories:

primary orbital meningioma (a form of ectopic meningioma)
- almost all are optic nerve meningiomas
- rarely ectopic rests of arachnoid cells give rise to orbital meningiomas separate from the optic nerve sheath ¹
secondary orbital meningioma
- represents 70-90% of orbital meningiomas ^1,3
- direct extension of intracranial meningiomas into the orbit
