title: [A case report of syphilitic meningitis with right oculomotor nerve palsy].
abstract: A 63-year-old man presented with acute-onset right ptosis and diplopia. The patient reported having engaged in unspecified sexual activities during his third decade and was found to have positive syphilitic serological findings at the age of 56 years. No clinical symptoms were noted at this time. On admission, he showed only right oculomotor nerve palsy. The patient's intelligence, gait and sensory functions were normal. Laboratory analysis revealed positive syphilitic serological findings and examination of the cerebrospinal fluid (CSF) further revealed pleocytosis, a higher IgG index and positive syphilitic reactions. A computed tomographic scan and other imaging studies were diagnostically nonspecific. We made a diagnosis of right oculomotor nerve palsy due to syphilitic meningitis. We treated the syphilitic meningitis with intravenous injections of penicillin G (24 million units per day for 21 days). Jarisch-Herxheimer reaction and other side effects were not apparent. We first made a thorough examination of the CSF to rule out diagnosis of meningitis, and pursued methylprednisolone pulse therapy (MPP, 1 g/day for 3 days) to treat the oculomotor nerve palsy. The ptosis and diplopia showed signs of improvement following the second MPP therapy session. The present case suggests that neurosyphilis is an important differential diagnosis for presentations of unspecific oculomotor nerve palsy and that MPP therapy may prove an effective treatment for it, even where there has been the long clinical onset.
