What are the routine examinations for glioma

We know that there are many types of tumors, among which brain tumors are the most serious. Glioma is a malignant tumor of the brain. If symptoms appear, you should go to the hospital for examination as soon as possible. So, what are the routine examinations for glioma?

1. Cerebrospinal fluid examination

The pressure usually increases during lumbar puncture. For some tumors, such as those located on the surface of the brain or within the ventricles, the amount of cerebrospinal fluid protein may increase, the number of white blood cells may also increase, and tumor cells may be found in some cases.

2. Ultrasound examination

It can help determine the side and observe whether there is hydrocephalus. For infants, a B-type ultrasound scan of the brain can be performed to show tumor images and other pathological changes.

3. Nuclear Magnetic Resonance

The diagnosis of brain glioma is more accurate than CT, the images are clearer, and it can detect tiny tumors that CT cannot show. Positron emission tomography can obtain images similar to CT, and can observe the growth and metabolism of tumors and distinguish benign from malignant tumors.

4. Radioisotope scanning

Tumors that grow quickly and have abundant blood supply have high blood-brain barrier permeability and high isotope absorption rate. For example, glioblastoma multiforme shows isotope concentration images, and there may be low-density areas in the middle due to necrosis and cysts. It needs to be distinguished from metastatic tumors based on its appearance and multiplicity.

5. Radiological examination

Including skull plain film, ventriculography, CT scan, etc. Skull plain film can show signs of increased intracranial pressure, tumor calcification and displacement of pineal calcification, etc. Ventriculography can show displacement of cerebral blood vessels and tumor blood vessels, etc. These abnormal changes are different in different types of tumors in different locations, which can help locate and sometimes even determine the nature of the disease.

6. Electroencephalogram

The EEG changes of gliomas are limited to changes in brain waves at the tumor site. On the other hand, they are generally widely distributed changes in frequency and amplitude. These are affected by tumor size, infiltration, degree of brain edema, and increased intracranial pressure. Shallow tumors are prone to local abnormalities, while deep tumors are less likely to have local changes.

If a patient is diagnosed with glioma, he or she should not panic, but maintain a good attitude and face it positively. Because glioma is highly malignant, comprehensive tumor treatment is recommended.
