A hydatid cyst is a parasitic illness that is caused by the larvae of Echinococcus granulosus. Hydatid cysts occur in the liver in 75% and in the lungs in 15% of cases. Central nervous system involvement is rare (perhaps as low as 1%), and the majority of such cases are observed in children. Headache and vomiting are the most frequently observed symptoms. In patients diagnosed with a hydatid cyst, imaging methods and serologic tests are very important for identifying cranial involvement. The most curative method is to remove the unruptured cyst using Dowling's method and to then wash the resulting gap with sodium chloride.
