Abstract
- Benign abducens nerve palsy is rare in children. Identifiable causes of abducens nerve palsy include neoplasm, elevated intracranial pressure, infection and trauma. Isolated abducens nerve palsy with unknown etiology is classified as benign or idiopathic. The diagnosis is made by excluding underlying pathologies. Prognosis is favorable. Most patients have been found to recover spontaneously within 6 months. Recurrent palsy is observed in some patients and is more pronounced in younger girls with left-sided palsy. Even the recurrent cases, however, are still benign. We report a case of benign abducens nerve palsy presenting diplopia and headache with normal results from MRIs and microbiologic studies. The patient underwent rapid, spontaneous recovery.
