Glioblastoma is a type of malignant tumor, which generally grows at a fast pace. In the early stages of the disease, the glioma often adheres to the surrounding tissues, posing significant challenges for future complete surgical removal. At the same time, extensive cerebral edema occurs around the glioma. If prolonged, this can lead to a serious increase in intracranial pressure, manifesting as repeated headaches, dizziness, nausea, and vomiting in the patient. Over time, this condition may also lead to optic nerve atrophy, resulting in decreased vision and visual field defects. Diagnosis generally benefits from cranial CT or MRI scans, but definitive diagnosis still requires surgical removal of the tumor. A small amount of tumor tissue is typically retained for pathological biopsy.
