title: Recurrent third nerve palsy as the presenting feature of neurofibromatosis 2.
abstract: Neurofibromatosis 2 (NF2) is a rare autosomal dominant disorder associated with the development of multiple central and peripheral nervous system tumors. Patients with NF2 are often diagnosed in adulthood, with symptoms of an isolated tumor or hearing loss associated with vestibular schwannomas. Diagnosing NF2 in children is complicated by the fact that the diagnostic criteria often are not met at presentation and there is usually no family history of the disease. The authors describe the diagnostic challenge posed by a pediatric patient who developed a relapsing and remitting third nerve paresis and was later diagnosed with NF2. A mechanism for the recurrent cranial mononeuropathy is proposed.
