[Cerebral venous thrombosis revealing neurosyphilis]

Syphilis is a bacterial infection which is increasing in France. Neurosyphilis is a rare manifestation of syphilis, mainly involving the meninges and the blood vessels. It is a rare cause of cerebral vascular stroke. Venous thrombosis of syphilitic origin is rarely described.

We reported a case of a fifty-year-old patient hospitalized for bilateral non-painful decreased visual acuity with headache. The CT scan showed cerebral venous thrombosis from the right lateral sinus to the jugular gulf. Patient presented a bilateral papillar oedema on the ocular fundus. Lumbar puncture showed lymphocytic meningitis with blood and CSF serology suggestive of neurosyphilis. The patient received antibiotic therapy with penicillin G for 14days with curative anticoagulation for six months. The evolution was favorable.

Cerebral venous thrombosis in neurosyphilis is a poorly described entity. This case report confirms the status of great simulator of syphilis. In the context of its worldwide recrudescence, syphilis must be evoked in front of an unexplained neurological disorder.
