Multiple sclerosis (MS) is also extremely uncommon in children. I describe an otherwise healthy ten-year-old boy who presented with a five day history of vertical diplopia with associated dizziness, decreased appetite, and unsteadiness. He had no recent history of infection and no previous history of neurological symptoms. Ophthalmologic assessment revealed full ocular ductions and right hyperdeviation in primary gaze during alternate cover test. This hyperdeviation increased during left gaze and right head tilt consistent with paresis of the right oblique muscle. Brain magnetic resonance imaging revealed multiple well-defined hyperintense T2 lesions in the periventricular and subcortical white matter, and brainstem, suggestive of MS. His symptoms resolved after 2 weeks with no treatment. To conclude, isolated trochlear nerve palsy can be the initial clinical manifestation of childhood MS. Long term follow up is needed to confirm the diagnosis of MS.  ISSN : 3189-4528  Journal Name : Neurosciences Journal  Volume : 2  Issue Number : 12  Publishing Year : 2007 AH 2007 AD  Article Type : Article  Added Date : Saturday, March 13, 2010  Researchers Researcher Name (Arabic) Researcher Name (English) Researcher Type Dr Grade Email محمد جان jan, Mohammed Researcher Doctorate   Files File Name Type Description  25896.doc doc   Back To Researches Page
