Introduction:
Neurosyphilis is rare today. It arises on average 20 years after poorly treated or untreated primary syphilis. Considering the decline in the incidence of syphilitic meningo encephalitis and the little known MRI aspects, we report the case of a patient affected by neurosyphilis occurring after primary syphilis untreated for 25 years.
Case Report:
A 65-year-old man presented typical clinical features including general paresis with psychiatric disorders, maniac access, and frontal syndrome as well as tabes dorsalis and Argyll-Robertson pupil. Brain MRI showed bilateral high intensity signals on the T2 weighted sequence located in mesiotemporal, insular, frontal regions.
Conclusions:
Very few cases of neurosyphilis with detailed brain MRI aspects have been reported. The interest of this case report is first to recall the importance of syphilitic serology in patients with subacute psychiatric disorders and secondly to present rarely reported aspects of the brain MRI.
