Abstract
Optic sheath meningocele is rare; only approximately 31 cases have been reported. The term optic sheath meningocele has recently been proposed by Garrity and Forbes to describe primary CSF cysts of the optic nerve sheath, without apical mass or malformation of the cranio-orbital junction. Presenting symptoms are often related to involvement of the optic nerve, with a slow or rapid decrease of visual acuity.
CT and MRI studies reveal a tubular-cystic enlargement of the optic nerve/optic sheath complex (on/onsc), with thickening of the optic nerve. Radiological differential diagnosis should include optic nerve tumors such as gliomas, meningiomas, and arachnoid cysts involving the optic nerve sheath. Up to now, it seems that early surgical management by means of optic nerve/optic nerve sheath decompression affords an improvent of visual function with minimal morbidity in patients who present a rapid decrease of visual acuity within 3–6 months.
We present an additional case and discuss the clinical, radiological, and operative features of this pathological condition of the optic nerve sheath.
