[Epidural hydatid cyst of the posterior fossa].

We report a case of epidural hydatid cyst in the posterior fossa in a 5-year-old child. The disease was revealed by raised intracranial pressure with torticollis. The diagnosis was based on the brain CT scan and MRI, and confirmed surgically. The course was uneventful. Cranial epidural hydatid cysts are very rare: only 18 cases have been reported previously in the literature.
