Symptoms of optic gliomas

summary

Neuroepithelial tumors are commonly referred to as gliomas, accounting for 40% - 50% of brain tumors. They are the most common intracranial malignant tumors. The annual incidence rate was 3~8 /10 population. Like other tumors, glioma is also caused by the interaction of genetic risk factors and environmental carcinogenic factors. Some known genetic diseases, such as neurofibromatosis (type I) and tuberculous sclerosis, are genetic predisposing factors of glioma. The incidence of glioma in patients with these diseases is much higher than that in the general population. Symptoms of optic gliomas? Let's talk about it

Symptoms of optic gliomas

The symptoms and signs caused by glioma mainly depend on the space occupying effect and the function of the affected brain regions. Glioma can cause headache, nausea and vomiting, epilepsy, blurred vision and other symptoms due to its space occupying effect.

In addition, because of its influence on the function of local brain tissue, it can also make patients have other symptoms. For example, optic glioma can lead to the loss of vision; Spinal gliomas can cause limb pain, numbness and muscle weakness; Gliomas in the central region can cause motor and sensory disturbance; Gliomas in the language area can cause difficulties in language expression and understanding.

Because of the different malignant degree of glioma, the speed of symptoms is also different. For example, patients with low-grade gliomas often have a history of several months or even last year, while patients with high-grade gliomas often have a history of several weeks to several months. According to the patient's history, symptoms and signs, we can preliminarily infer the location of the lesion and the degree of malignancy.

matters needing attention

After surgical treatment, patients with high-grade glioma often need further radiotherapy. For patients with low-grade gliomas, if there are high-risk factors (such as tumor volume more than 6 cm, incomplete resection and other factors), radiotherapy should also be considered. Radiotherapy includes local radiotherapy and stereotactic radiotherapy. Stereotactic radiotherapy is generally not used for the first discovery of glioma. According to the different technology, local radiotherapy can be divided into intensity-modulated radiotherapy and three-dimensional conformal radiotherapy. For patients with recurrent gliomas, especially those in the functional area, sometimes stereotactic radiotherapy can be considered.
