What are the hazards of glioma

Glioma is familiar to everyone. It is common in young male friends. Relevant epidemiology shows that the incidence of glioma is increasing year by year. Oncology experts suggest that glioma should be detected and treated early to prevent serious complications. So, what are the hazards of glioma?

1. The tumor damages the surrounding tissues, infiltrating and destroying them, and causing corresponding focal symptoms. That is, wherever the tumor grows, it will damage that area. If it grows to the frontal lobe, it will affect memory, emotions, spirit, language, personality, thinking, etc. If it grows to the parietal lobe, it will affect limb movement, limb sensation, urination, and defecation. If it grows to the occipital lobe, it will affect vision and field of vision. If it grows to the cerebellum, it will affect the coordination function of the whole body. If it grows to the brainstem, almost all the symptoms you can think of will appear!

2. As the glioma grows, the local intracranial pressure is the highest, and a pressure gradient is generated between the various intracranial cavities, causing brain displacement. Gradually worsening, brain herniation is formed. Supratentorial cerebral hemisphere tumors can cause subfalcine herniation, and the cingulate gyrus can move across the midline, which can cause wedge-shaped necrosis. The pericallosal artery can also be compressed and displaced, and severe cerebral infarction in the supply area can occur. More important is the tentorial notch herniation, that is, the medial sulcus of the temporal lobe shifts and herniates through the tentorial notch to the posterior cranial fossa. The ipsilateral oculomotor nerve is compressed and paralyzed, the pupil is dilated, and the light reaction disappears. The cerebral peduncle of the midbrain is compressed to produce contralateral hemiplegia. Sometimes the contralateral cerebral peduncle is compressed on the edge of the tentorium or the tip of the bone, producing ipsilateral hemiplegia. The posterior choroidal artery and the posterior cerebral artery can also be compressed, causing ischemic necrosis. Finally, compression of the brainstem can produce downward axial displacement, leading to infarction and hemorrhage in the midbrain and upper pons.

The harm of glioma cannot be ignored. If it is not treated in time, patients with glioma will have various complications, which will seriously affect the patient's health. In fact, glioma is not terrible. As long as it is discovered in time and the patient is treated systematically, the condition of patients with glioma can be improved or even completely cured.
