[Congenital syphilitic meningomyelitis manifested in the adult].

We report a case of neurosyphilis of the spinal cord in a 38-year-old-man presenting with urinary incontinence and Argyll-Robertson sign. Anamnesis revealed the congenital origin of the disease. Urodynamics findings were consistent with a conus medullaris involvement and CSF study revealed a specific lymphocytic meningitis. A specific spinal arteritis was found by angiography. A quarterly 15 to 20 days course of intravenous penicillin was then instituted during 2 years. A specific treatment of urinary symptoms resulted in complete disappearance of sphincter dyssynergia. Antibiotic therapy was followed by clinical improvement and regression of most of the CSF abnormalities.
