The most common intracranial tumor is

There are many types of intracranial tumors. Some are benign, and some are malignant. But no matter what type of intracranial tumor it is, we should pay attention to it, because there is a high probability that the intracranial tumor will compress other nerves in the skull. Moreover, some malignant intracranial tumors can seriously threaten a person's life and health. Today, we will give you a detailed introduction to the relevant types of intracranial tumors.

Intracranial tumors are most likely to occur in the cerebral hemispheres. Different tumors have different predilection sites. Among intracranial tumors, gliomas are the most common. Tumors can be divided into benign and malignant according to their nature. The symptoms will vary depending on the location of the tumor.

It is still recommended to take surgical treatment, and radiotherapy can also be used. The final nature of the tumor can be confirmed in the postoperative pathological diagnosis of the disease. In addition, intracranial tumors are mostly found in adults and children under one year old.

The most common sites of brain tumors

The most common site of intracranial tumors. Generally, intracranial tumors are divided into primary and secondary, and also into benign and malignant. Regarding secondary malignant tumors, that is, metastatic malignant tumors, they usually occur at the junction of gray and white matter. Primary intracranial malignant tumors, such as meningiomas, are usually found on the surface of the brain tissue, in the pontocerebellar triangle, or around deeper blood vessels. As for intracranial germ cell tumors, the most common sites are the pineal region and the sella turcica of the pituitary gland. For craniopharyngioma, the most common site of occurrence is generally in the sellar region. The most common site of esophageal membranous tumors is the posterior cranial fossa. Gliomas can occur anywhere in the brain.

What are the three common classifications of intracranial tumors?

1. The classification of benign and malignant intracranial tumors is the same as that of all tumors. Intracranial tumors are also divided into benign and malignant. Among them, the most common malignant brain tumor is glioma, but there are also many benign tumors, including pituitary tumors, meningiomas and neurothecomas.

2. Intracranial tumors can be divided into primary and secondary types. Among them, primary brain tumors account for a large proportion of primary tumors of the central nervous system. Primary brain tumors arise from various intracranial tissues, such as brain parenchyma, meninges, blood vessels, nerves, pituitary glands, and embryonic residual tissues. Gliomas are the most common, followed by meningiomas.

3. There is also a WHO classification for intracranial tumors. Intracranial tumors are divided into seven categories: neuroepithelial tumors, peripheral nerve tumors, meningeal tumors, lymphomas and hematopoietic cell tumors, germ cell tumors, sellar region tumors and metastatic tumors. Therefore, the classification of intracranial tumors is extremely complex.
