Abstract
A 69-year-old woman presented with an 8-month history of diplopia and examination findings consistent with a right third-nerve palsy. Head MRI identified the presence of a 5.8 mm, nodular, isointense lesion in the suprasellar cistern, which demonstrated enhancement with gadolinium contrast. The lesion did not show any evidence of growth over a 3-month follow-up period. These MRI findings, alongside the clinical features, suggest oculomotor nerve schwannoma. Oculomotor schwannomas are a rare cause of third-nerve palsy. The presenting features and management options for oculomotor schwannomas are discussed to provide a framework for the diagnosis and management of these patients.
