Abstract:

The optic nerve sheath meningioma is a rare tumor. The painless and progressive loss of vision is the main clinical sign. It was a 38-year-old woman who suffered from painless and progressive right exophthalmia for two months. The clinical exam revealed a loss of visual acuity with a visual field defect. The orbital CT showed calcified thickened of the right optic nerve, causing exophthalmia without the involvement of intraorbital fat or muscles. The diagnosis of optic nerve sheath meningioma was strongly evoked. Radiotherapy is offered first before discussing a complementary surgery.
