Glioma is a tumor originated from glial cells and neuronal cells of the nervous system, most of which are malignant. Cerebral aneurysm is an aneurysm formed when the arterial vessels inside the brain are abnormally inflated, which is not a substantial tumor. 1. Cerebral glioma: Cerebral glioma is a relatively common malignant tumor in the brain, which can be divided into various types. Its malignant degree is relatively high, its growth speed is relatively fast, its course is short, and it is easy to have infiltrative growth. Surgery is ineffective, difficult to completely remove and easy to recur, and it needs to be supplemented with radiotherapy or chemotherapy after surgery, and the prognosis is relatively poor. 2. Cerebral aneurysm: Cerebral aneurysm is a tumor-like bulge produced by local abnormal changes in blood vessels, which is not a malignant tumor, but prone to rupture and cause bleeding. For unruptured aneurysms, surgery can be used to achieve good therapeutic effect, usually using craniotomy and minimally invasive interventional embolization two surgical methods. It is recommended that the patient go to the hospital for a clear diagnosis and timely treatment under the guidance of the doctor.
