[Normotensive hydrocephalus as a manifestation of meningovascular syphilis].

Progressive general paralysis, tabes dorsalis and meningovascular syphilis are different manifestations of tertiary syphilis. The clinical picture of meningovascular syphilis is of a subacute or chronic meningeal syndrome. It may be associated with focal neurological signs of cerebral arteritis. Inflammation of the leptomeninges may impede circulation of the cerebrovascular fluid at different levels, giving rise to noncommunicating, or exceptionally to communicating hydrocephalus. Diagnosis of this depends on the clinical signs and neuro-imaging changes. We present the case of a man with meningovascular syphilis who developed clinical signs of normotensive hydrocephalus.
