Syphilitic cerebral vasculitis: diagnostic possibilities

We studied 1387 patients with different forms of syphilis for neurological deficiency. Thirty patients had vascular neurosyphilis. Two cases are described in detail. A 40-year-old man had recurring episodes of acute disturbance of the cerebral blood flow and progressive cognitive disorders. A 32-year-old patient presented with progressive dementia, hallucinatory symptoms and minor multifocal neurological changes. The diagnosis of neurosyphilis was verified by CSF-test results. The diagnosis of cerebral vasculitis was proved by the data of magnetic resonance imaging (MRI), magnetic resonance (MR) angiography, ophthalmological methods, and duplex scanning of brachiocephalic arteries, transcranial duplex scanning. Diagnostic criteria of syphilitic cerebral vasculitis were defined and presented.
