Neurosyphilis révélée par une atteinte multiple des nerfs crâniens : apport de l'imagerie par résonance magnétique nucléaire

Such MRI abnormalities are not specific and can be observed in various tumoral, auto-immune and infectious diseases. They can also mimic neurofibromatosis type II. Cranial nerve involvements in neurosyphilis can result from nerve inflammation in basal meningitis, nerve ischemia in meningovasculitis or from compression by an adjacent gumma. In our case, the cranial neuropathy was related to a mixed meningovascular and parenchymatous form of neurosyphilis.
