Sudden Onset Monoparesis and Dysarthria in a 5-Year-Old boy: A Case Report

Abstract

Introduction: Moyamoya disease (MD) is a disorder caused by blocked arteries at the base of the brain. As the normal blood vessels narrow and become blocked, a person may suffer a stroke. The MD mainly affects children, although adults may have the condition. This is a rare condition, with a marked prevalence gradient between Asian countries. Case Presentation: We report a 5-year-old boy, who was presented with sudden right hand monoparesis and dysarthria. Conclusions: The patient was investigated with magnetic resonance angiography and diagnosed as MD.
