Late symptoms of glioma?

summary

Glioma is a kind of tumor that does great harm to human body. At the beginning, people often don't notice it. With the increase of tumor, it oppresses the surrounding tissue, and patients only go to the hospital when there are related symptoms. What's more, some patients only go to the hospital when they are in the late stage. Late symptoms of glioma? Let's talk about it

Late symptoms of glioma?

Can produce optic papilla edema, and long-term secondary atrophy of the optic nerve, vision decline. The primary atrophy of optic nerve and the decrease of visual acuity were found in patients with optic nerve compression by tumor. Abducens nerve is easily compressed and involved, often causing paralysis and diplopia.

Most of them are caused by the increase of intracranial pressure, the growth of tumor, the gradual increase of intracranial pressure, and the compression and involvement of intracranial pain sensitive structures. Headache can be mainly in the affected side, headache began intermittently, mostly occurred in the early morning, with the development of tumor, headache gradually aggravated, lasting longer.

It is caused by the stimulation of medullary vomiting center or vagus nerve. There is no nausea in the first place, and it is ejective. In children, because of the separation of cranial suture, headache is not significant, and because the posterior fossa tumor is more common, so vomiting is more prominent.

matters needing attention

The purpose of operation is to make clear the diagnosis, improve the symptoms and reduce the tumor load. The principle of operation is to cut the tumor as much as possible, reduce intracranial pressure, and reduce the compression of tumor on important tissues and nerves on the premise of preserving important nerve function.
