Neurosyphilis is a rare manifestation of syphilis that affects the nervous system, including the brain and spinal cord. It can present in various forms, such as a solitary syphilitic gumma, incomplete Brown-Séquard syndrome, or meningovascular syphilis. Diagnosis is often challenging due to non-specific imaging findings and positive serological tests for syphilis. Despite being a major complication of syphilis, neurosyphilis remains a public health problem that requires prompt diagnosis and treatment. It is important to note that not all cases of neurosyphilis follow the typical Brown-Séquard type, highlighting the complexity and variability of this condition.
