This is a big question, because the triventricular tumors originate from different regions and different parts of the brain, and the treatment is definitely just not the same. In our specialty, the ventricular tumors are divided into anterior, middle and posterior portions, and the anterior portion originates from craniopharyngiomas, pituitary tumors, teratomas in the saddle region, and even some gliomas in the hypothalamus, which can be treated with a great deal of help after the development of microneurosurgery nowadays. With our microsurgical advances, some tumors originating from the hypothalamus, our surgical treatments are very effective, and the results are more satisfactory. Those originating from the posterior part, such as some pineal tumors, in addition to the original pathological examination, craniotomy is of great help to such tumors, so we can not simply ask whether the three ventricles of the brain tumor can be treated or not, any intracranial tumors with the development of microscopic neurosurgery nowadays, there is a therapeutic value and therapeutic help.
