What are the main complications of the optic nerve sheath meningioma?
Optic nerve atrophy and ischemic retina.
Well-defined lobulated margin solid mass lesion axial width up to 30 x 22 mm and height up to 25 mm in left orbital cavity intraconal middle to posterior part with impression on the adjacent orbital medial wall, related extraocular muscles, the posterior uveo-scleral layer of the eye, and posterior margin of lacrimal gland orbital part are seen. The mass has completely encased the optic nerve sheath complex, leading to left side proptosis, lacrimal gland, proptosis, and lacrimal gland and preseptal soft tissue swelling. Minimal extension of the mass within the optic canal distal segment seems to be also present.
