Third nerve palsy as a presenting feature of neurofibromatosis 2 – A case report

Abstract

Neurofibromatosis 2 is an inheritable disorder characterized by bilateral vestibular nerve schwannomas. The usual presentation of such patients is hearing loss and difficulties with balancing. However, we report a case of a 20-year-old female presenting with a long-standing 3rd nerve palsy without any hearing disturbances. Although it is a rare presentation, neuroimaging must be performed in all cases of nerve palsies to rule out any CNS manifestations. Management in such conditions should be multidisciplinary especially under the leadership of a neurologist as the cardinal complications are central.
