Metastatic symptoms of glioma?

summary

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

Metastatic symptoms of glioma?

The course of glioma varies according to its pathological type and location. The time from symptoms to treatment is usually weeks to months, and a few can be years. The history of tumors with high degree of malignancy and posterior fossa is shorter, and that of benign tumors or tumors located in the so-called quiet zone is longer. If the tumor has bleeding or cyst formation, the development process of symptoms can be accelerated, and some can even be similar to the development process of cerebrovascular disease.

There are two main symptoms. One is intracranial pressure and other general symptoms, such as headache, vomiting, vision loss, diplopia, seizures and mental symptoms. The other is the local symptoms caused by the compression, infiltration and destruction of brain tissue by tumor, resulting in the loss of nerve function.

Headache is mostly caused by increased intracranial pressure, tumor growth, increased intracranial pressure, compression, involving intracranial pain sensitive structures such as blood vessels, dura and some cranial nerves and headache. Most of them are throbbing pain and distending pain, most of them are located in frontotemporal or occipital part, and the tumors are shallow in one side of the cerebral hemisphere. Headache can mainly occur on the affected side, and the headache starts intermittently. It mostly occurs in the morning. With the development of the tumor, the headache gradually worsens and lasts longer.

matters needing attention

Vomiting is caused by stimulation of the medulla oblongata vomiting center or vagus nerve. 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.
