A personalized approach to the treatment of hydrocephalus associated with medulloblastoma in children

To this day, there is no Class I (A) evidence base that could serve as a guideline for the treatment of tumor-associated hydrocephalus in children. Tumors of the posterior cranial fossa (PCF), due to their special interaction with the cerebrospinal fluid pathways, are most often accompanied by the development of hydrocephalus. It is debatable which treatment tactics should be applied correctly: whether to install an external ventricular drainage or a ventriculoperitoneal shunt, whether to perform an endoscopic triventriculostomy, or postpone the procedure of cerebrospinal fluid removal until resection of the tumor. This does not exclude the progression of post-resection hydrocephalus, which occurs in 37 % of cases in the pediatric population.
