Intra-cranial cyst

Arachnoid cysts are relatively common benign lesions occurring in association with the central nervous system, both within the intracranial compartment (most common) as well as within the spinal canal. They are usually located within the subarachnoid space and contain CSF. Most frequently (50-60%) arachnoid cysts are located in the middle cranial fossa, where they invaginate into and widen the sylvian fissure.

Hydatid cysts of the brain.

Brain involvement with hydatid disease occurs in 1-2% of all Echinococcus granulosus infections. Cerebral hydatid cysts are usually supratentorial, whereas infratentorial lesions are quite rare

Hydatid cyst of the brain presents clinically as intracranial space occupying lesion and is more common in children. Surgery is the treatment option with affordable morbidity and low mortality.
