title: Pure motor hemiplegia due to meningovascular neurosyphilis.
abstract: Two young male homosexuals developed prodromal syndrome followed by penicillin-responsive meningitis and the acute onset of pure motor hemiplegia. The clinical and laboratory features are consistent with meningovascular neurosyphilis. Basis pontis infarctions were subsequently demonstrated on magnetic resonance imaging scans. To our knowledge, this is the first description of syphilitic arteritis as a pathophysiologic basis for pure motor hemiplegia.
