G - 3 Accidents vasculaires cérébraux à répétition sur dolichoectasie du tronc basilaire malgré un traitement antithrombotique

Severe Hydrocephalus due to Obstructive Basilar Dolichoectasia of the Third Ventricle

“…All of these factors were present in our patient. Brain CT scanning, cerebral MRI or cerebral arteriography are helpful for diagnosis [3,4] . A cerebral CT scan without contrast can show hyperdensities corresponding with calcifications in the wall of the dolichoectasia and can also help to identify the mechanisms responsible…”
