How to check for glioma

How to check for glioma? Glioblastoma is a very special head tumor disease and one of the few terminal malignant brain tumors in humans. The harm it causes to the human body can be imagined. When symptoms appear, go to the hospital for examination in time. Let us learn how to check for glioma.

1. DSA examination: MRI and CT scans have reduced the use of angiography, but angiography can still be used to observe the blood supply and drainage vessels of the tumor. In addition, the blood vessels supplying the tumor can be embolized to facilitate surgical treatment.

2. Skull X-ray: Conventional skull X-rays have limited role in the diagnosis of brain tumors. They can show bone resorption, enlarged sella turcica (suggesting pituitary adenoma) or "empty sella turcica". They can also show osteolytic or mitral metastasis of the calvaria and skull changes caused by other tumors, such as meningioma, chordoma, acoustic neuroma, and paranasal sinus tumors. Abnormal calcification in the skull (especially craniopharyngioma and slow-growing oligoglial cells and astrocytomas) can also be seen.

3. Head CT examination: CT is one of the basic tools for screening and diagnosing intracranial tumors.

4. Magnetic resonance imaging (MRI): MRI is superior to any previous technology in displaying normal brain anatomy. MRI can detect pituitary microadenomas earlier than CT and is one of the means to detect small intracranial tumors and vascular malformations at an early stage.

5. Cerebrospinal fluid examination: The pressure of lumbar puncture is usually increased. For some tumors, such as those located on the brain surface or in the ventricles, the amount of cerebrospinal fluid protein may increase, the number of white blood cells may also increase, and some tumor cells may be found. However, for those with significantly increased intracranial pressure, lumbar puncture has the risk of promoting brain herniation. Therefore, it is generally only performed when necessary, such as when it is necessary to distinguish from inflammation or bleeding. For those with obvious pressure increase, the operation should be cautious and do not release too much cerebrospinal fluid. Mannitol drip is given after surgery and careful observation is required.

The above is the general diagnosis method for brain glioma. I hope it will be helpful to you and I wish you good health.
