Small nodules isodense to gray matter at the lateral walls of both lateral ventricles suggesting subependymal heterotopia.

Right parasagittal interhemispheric cyst.
Cystic lesion at the right aspect of the posterior cranial fossa causing mass effect on the right cerebellar hemisphere suggesting arachnoid cyst.
