cranial nerve palsies
occurs approximately 20 to 30 years after the initial exposure to T. pallidum as a result of progressive meningoencephalitis with resultant
tissue invasion with spirochetes, chronic perivascular and meningeal inflammatory changes and meningeal fibrosis.
slowly progressive degenerative form of syphilis involving the posterior columns (demyelination) and posterior roots (inflammatory change with fibrosis) of the spinal cord
