Lateral ventricular neuroblastoma accounts for less than 1% of intracranial tumors and is a benign tumor, but the size of the tumor is often already large when it is found, plus the tumor is located in the deep part of the brain with rich blood supply, making the surgery difficult and risky. The mortality rate is generally considered to be more than 5%. However, if a reasonable surgical approach can be adopted and proper surgical techniques can be mastered, the long-term effect of this kind of tumor is very good, the recurrence rate is low, and it can even be cured. My personal experience is: 1. It is best to use the corpus callosum approach. Generally speaking, if the length of the corpus callosum is not too large, the loss of union syndrome will not occur after surgery; even if it occurs, it can be recovered. 2. Such tumors must be fully resected or nearly fully resected in order to ensure that the patient can smoothly pass the operation period after surgery. It is very easy to have intracerebral hematoma. 3. Care must be taken to protect the blood vessels in the deep brain, especially the veins. 4.Although these tumors are sensitive to radiotherapy, few tumors shrink or disappear immediately after radiotherapy, and the tumors appear size change more than half year after radiotherapy. Therefore, radiotherapy is an adjuvant treatment after tumor removal.
