Syphilis is a systemic disease caused by the spirochete Treponema pallidum which can compromise the central nervous system at any stage and whose clinical presentations have been modified in recent decades. Were port the case of a 16 years old male with a 3-years history of sexual risk behavior and syphilis with no treatment who experienced headache and decreased vision for four months. Initial assessment showed right homonymous hemianopia, bilateral papilledema and left exudative retinopathy. Serological tests for syphilis: reactive HIV: non-reactive. Brain MRI revealed a single irregularly enhancing lesion in the left occipital lobe. He received treatment for syphilis for three days, and stereotactic biopsies were performed by the initial suspicion of brain tumour. Histological examination showed a chronic granulomatous consistent with neurosyphilis. In his read mission, greater affectation of acuity and visual field defect was evident. Visual evoked potentials: absent in both eyes. Penicillin G sodium was initiated for 4weeks (for evidence of improvement imagenological)associated with corticosteroids, showing serological and discrete clinical improvement at the end of treatment decreased. The gummatous neurosyphilisis a rare form of tertiary syphilis which ever considered as differential expansive intracranial lesions in HIV-seronegative individuals with reactive syphilis serology.
