Neuroendoscopic transventricular ventriculocystostomy constitutes a valid alternative to microsurgery for intracranial cysts located within or adjacent to the ventricles. It creates an effective CSF flow within the cyst with minimal alteration of subarachnoid spaces. It may be combined with an ETV procedure in case of obstruction of CSF pathways and should be preferred to the insertion of shunts ¹⁾.
