 Intraventricular tumors often cause hydrocephalus because their location in the ventricles affect cerebrospinal fluid circulation. Even small tumors can lead to acute hydrocephalus when they block the cerebrospinal fluid flow. They may also be found as large tumors occurring in large spaces, such as in lateral ventricles.

 Since various histological tumors occur in ventricles, it is important to consider the treatment strategy according to the expected histological type before treating hydrocephalus in the early stage. In addition, it is beneficial to predict and evaluate the site and size of the tumor, the cause of hydrocephalus, and the effect of postoperative chemotherapy and radiation therapy. Some tumors are sensitive to chemotherapy and radiation therapy, so there is an advantage in performing a biopsy at the same time as hydrocephalus treatment.

 Ventricular drainage and ventricular peritoneal shunts for patients with high intracranial pressure are at risk of developing ascending hernias, so we should be careful with the procedure.
