Abstract

Syphilis is an infectious venereal disease caused by the spirochete Treponema pallidum. Neurosyphilis is a clinical form that can occur at any stage of the disease, presenting itself with signs and polymorphic neurological symptoms that may mimic multiple disorders of the central nervous system. Thus, it is included in the differential diagnosis of many diseases, justifying the need for description of different forms of otosyphilis. This study reports two patients showing a rare form of presentation, demonstrating an exclusive and simultaneous involvement of the VII and VIII cranial nerves and the membranous labyrinth, cochlea and semicircular canals, without other neurological manifestations.
