Abstract:
Hydatidosis is an endemic disease in Morocco. Cerebral echinococcosis is a relatively rare entity accounting for only 1-2% of all hydatid cysts in humans. Extradural hydatid cyst of the posterior fossa is a very uncommon site for the disease: only four cases have been reported in the literature. We report the case of a 37-year-old admitted for high intracranial pressure. Brain MRI showed an extradural and extracranial posterior fossa cyst without enhancement after contrast medium injection. Multiple hydatid cysts were removed and the histological examination of the tissue sample confirmed the diagnosis. The patient was given albendazole postoperatively with good follow-up 6 months later.

Cranial Bones: Superior and Posterior View
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...
