Abstract
Cystic hydatidosis caused by Echinococcus granulosus is a rare disease which mainly involves the liver and lungs. In 1%-2% cases, it may affect the brain. Primary multiple hydatid cysts of the brain are very rare. A 14-year-old girl presented with a history of headache and altered sensorium. Computed tomography scan and magnetic resonance imaging showed multicystic intraventricular lesions and patient was operated by neurosurgeon. Multiple cysts were removed. Antihelminthic medication was started, and patient was discharged with full recovery of neurological function. Hydatid cyst must be considered as a differential diagnosis of cystic space-occupying lesions of the brain. Surgery and antihelminthic drugs will help to get rid of infection.
