title: Intracranial and orbital hydatid cysts.
abstract: Parasitic diseases involving brain and orbit are relatively rare in Tunisia; the most frequently encountered is the hydatid cyst, 55 examples of which were seen since CT scanning was introduced into Tunisia 2 years ago. Various aspects of the intracerebral and orbital hydatid cysts are reported and a tentative classification is made based on characteristics revealed by CT.
