Multiple cerebral hydatid cysts: a surgical challenge.

Hydatid disease is common in the developing countries of South Asia. The rate varies from 10-15 out of every 500 intracranial lesions. Primary hydatid disease of the brain is a rare entity. Most cases of cerebral hydatidosis are associated with disease in the liver, lungs or other organs. The number of cysts is variable, but may range from one to ten. We report a case of primary cerebral hydatid disease in which 25 cysts were evacuated intact from a single hemisphere and the patient showed complete neurological recovery.
