RESUMO
Only 0.5 to 2% of hydatid cysts are localized in the skeleton and of these, 3 to 4% are found in the skull. In this paper, the authors report a case of primary hydatidosis involving the cranial vault revealed by a bulging mass of the forehead and symptoms of raised intracranial pressure that occurred in a 22-year-old woman who came from a rural area. Through this case and literature review, the authors analyse the epidemiological, clinical and radiological aspects of skull hydatidosis. They conclude that hydatid cyst should be considered in the differential diagnosis of any soft tissue swelling or osteolytic lesion in the scalp of patients living in endemic areas.

Intracranial alveolar echinococcosis is uncommon. We report a patient with right frontal lobe and palpebral lesions secondary to a primary hepatic focus with secondary lesion in the lung. The intracranial and palpebral cystic masses were totally removed and both proved to be alveolar hydatid cysts. An unusual feature in this case is CT and MRI demonstration of dural and bony extension.
