The treatment of extracerebral ventricular neuroblastoma mainly includes general treatment, surgical treatment and auxiliary treatment. 1. General treatment: pay attention to rest and ensure sufficient sleep. At the same time, eat more nutritious food to ensure balanced nutrition. 2. Surgery: it is the main treatment method. Although extracerebral ventricular neuroblastoma is considered a benign tumor, it has invasive biological characteristics (e.g. atypical histological features and high cell proliferation rate), and early treatment is recommended. 3. Adjuvant therapy: Because the tumor is sensitive to radiotherapy, postoperative patients should be treated with radiotherapy routinely. It is recommended that patients should seek medical treatment in time and choose the appropriate treatment plan according to their own conditions under the guidance of doctors, so as to avoid delaying the condition and causing serious consequences.
