Abstract

Series of 12 patients, diagnosed with intracranial schwannomas, were reviewed retrospectively in the last 2 years. 50% were males and 50% were females. The age varied between 22 and 70 years. Based on the location 8 were cerebello-pontine angle lesions, 2 trigeminal, 1 lower cranial nerve and 1 orbital apex.

Optic atrophy was seen in 41% patients & papilledema was seen in 25%. Reduced corneal sensation was reduced in 33% patients. 3rd cranial nerve was involved in 8% of patients, 5th nerve in 25% and 6th nerve in 50%, 7th nerve in 50%, 8th nerve in 50 % and 9th and 10th nerve involvement in 8%. Nystagmus was seen in 16%.

Intracranial schwannomas have varying presentations. Detailed evaluation and neuroimaging are essential. The neuro-ophthalmologist along with the neurosurgeon play a key role in the diagnosis and management in the pre and post operative period.
