What is an optic nerve sheath?

Optic Nerve Sheath Meningiomas (ONSM) are uncommon, benign neoplasms originating from the meningothelial cells of the meninges surrounding the optic nerve. The tumor may arise from either the intraorbital or intracanalicular portions of the optic nerve where there is a meningeal sheath. Primary ONSM should be differentiated from secondary intracranial meningiomas that extend anteriorly to involve the optic nerve. Although considered benign tumors, primary ONSMs cause slow, progressive vision loss secondary to compression of the adjacent optic nerve and its blood supply. This monograph discusses primary ONSM.

What is the second most common primary optic nerve tumor?

Although rare, ONSM is the second-most common primary optic nerve tumor and represents 1-2% of all meningioma.. They account for one-third of primary optic nerve tumors. The incidence of ONSM is highest in adult women in the fourth or fifth decades of life, with women being three times more likely than men to be affected. ONSM however can rarely occur in children: a review of cases by Dutton showed that only 4% of tumors occurred in patients younger than 20 years.

What is the diagnosis of ONSM?

The diagnosis of ONSM is clinical and then confirmed with neuroimaging. Although computed tomography (CT) of the head and orbit may show the lesion (especially if calcified), magnetic resonance imaging (MRI) of the head and orbit with gadolinium and fat suppression sequences is generally recommended for ONSM. The CT scan findings include diffuse, tubular, lesions with contrast-enhancement. Calcifications may be present within the tumor as well and are better seen on CT. MRI studies of the head and orbit with gadolinium contrast as well as fat suppression sequences are useful for identifying the involvement of the sheath and the radiographic features are usually so typical for ONSM that a biopsy may not be necessary in the appropriate clinical setting. MRI may demonstrate diffuse, tubular thickening of the optic nerve sheath encasing the optic nerve, often producing a characteristic "tram track" sign on axial cuts or a "doughnut" sign on coronal cuts. The tumor usually enhances homogenously and vigorously after contrast infusion. MRI may also be useful in delineating the extent of the tumor and for evaluating for intracranial extension. Ga-68 PET/CT has recently been considered as a diagnostic tool for the detection of meningiomas via exploitation of their somatostatin receptor ligands. Sensitivity and selectivity was found to be 10% higher in the detection of primary or recurrent meningiomas compared to MRI and has also shown high potential in its ability to predict tumor growth rate. PET scan is usually not necessary for the diagnosis of typical ONSM, however. Biopsy of the tumor is not necessary for diagnosis in typical clinical cases with characteristic radiographic features for ONSM and surgery carries a high risk of damage to the optic nerve.

What is ONSM asymptomatic?

Patients with ONSM may be asymptomatic. Symptomatic patients with ONSM most often present with gradually progressive, painless monocular vision loss. Visual acuity at presentation can vary considerably (20/20 to no light perception) due to variable levels of awareness of visual loss. Dutton's review found that 24% of patients had visual acuity of counting fingers or worse, while 45% of patients had visual acuity of 20/40 or better. Evidence of optic nerve dysfunction (e.g., reduced color vision, visual field loss, an ipsilateral relative afferent pupillary defect, and optic atrophy/optic disc edema) are typically present. Patients may demonstrate a classic clinical triad of ONSM: 1) painless, slowly progressive vision loss, 2) optic atrophy, and 3) so called “optociliary shunt vessels." The full triad however is seen in only a minority of cases, however. “Optociliary shunt vessels” are collateral vessels formed in response to chronic occlusion of the central retinal vein (and not a true shunt) and serve to carry blood from the retinal venous circulation to the choroidal circulation (i.e., retinochoroidal venous collateral). These retinochoroidal venous collaterals (RCVC) however are not specific for ONSM. In addition, RCVC are seen in only 30% of patients with ONSM. Patients with orbital ONSM may also have proptosis or extraocular motility deficits, depending on the location and size of the tumor. Funduscopic exam may reveal an initially normal or swollen optic disc, but eventually optic atrophy develops (with or without RCVC).

Can ONSM be observed?

Patients with ONSM may be observed if asymptomatic and generally the clinical course and imaging are sufficient to make the diagnosis. Although the lesions are typically histologically benign, symptomatic patients could be offered treatment. The optimal timing of treatment for ONSM is unclear due to the difficulty in predicting the variable natural course of an individual tumor. One case series found a high degree of variability of the change in visual acuity from baseline for 16 patients diagnosed with ONSM whom were then followed expectantly for an average of 6.2 years There were additionally no clear variables identified which could help predict the patients' visual outcomes other than an already poor initial visual acuity.

Is ONSM a cytogenetic abnormality?

ONSM have also been associated with neurofibromatosis type 2. The most common cytogenetic abnormality found in meningiomas is the loss of the long arm of chromosome 22, including the region containing the NF2 gene.

Is RCVC specific for ONSM?

These retinochoroidal venous collaterals (RCVC) however are not specific for ONSM. In addition, RCVC are seen in only 30% of patients with ONSM. Patients with orbital ONSM may also have proptosis or extraocular motility deficits, depending on the location and size of the tumor.

What is the best treatment for meningioma?

Radiation therapy . Stereotactic fractionated radiotherapy is the preferred modality as adjuvant treatment after surgery for meningioma in general and is the preferred primary modality of treatment for meningiomas that are in close proximity to important neurovascular structures such as the optic nerve.

Can optic nerves be resectioned?

For tumors infiltrating the nerve, resection is limited to the exophytic part, unless the eye has no light perception, in which case the optic nerve can be transected. As an alternative to surgical resection of the tumor, a window can be created in the dura to relieve pressure on the optic nerve (OPRS 2006; 22:278).

Can breastfeeding cause meningioma?

Women who report breastfeeding for more than 6 months are at decrease d risk of meningioma (J Neurosurg 2013; 118:649). Reproductive factors such as age at menarche, age at menopause, and parity have not been found to increase risk, despite the known increase in tumor growth during pregnancy (J Neurosurg 2013; 118:649).
