Cortical speech disorders rarely occur in multiple sclerosis (MS).
We report a patient with relapsing-remitting MS, who presented with acute verbal dyspraxia.
Magnetic resonance imaging (MRI) demonstrated an acute T2/Flair hyperintense, primarily white matter lesion underlying the middle third of the inferior frontal gyrus.
The verbal dyspraxia cleared beginning 48 hours after the initiation of iv dexamethasone.
Follow-up MRI demonstrated qualitative and quantitative diminution of the hyperintensity.
This is the first report of a clinically definite MS patient with acute verbal dyspraxia.
Moreover,there was a suggestive localization of verbal praxis to Brodmann areas 44/45.
