What symptom is brain stem tumor later period

summary

Brain stem tumors are usually located in the pons, and are expansive growth, but astrocytomas can occur in any part of the brain stem, generally invasive growth. Almost all tumors are gliomas, mainly astrocytoma and glioblastoma multiforme, and glioblastoma in the lower part of the brain stem. What are the causes of brain stem tumors? Now let's share the etiology of brain stem tumor with you. Let's take a detailed look.

What symptom is brain stem tumor later period

Brain stem tumors are usually located in the pons, such as tumor growth fast, high degree of malignancy, indicating that bleeding, necrosis, and even cystic deformation may occur. Generally speaking, the nature of tumors is almost glioma, astrocytoma and glioblastoma multiforme.

Second, the etiology of brainstem tumors. 2. If the tumor and the surrounding normal brainstem nerve tissue are not bounded, this situation belongs to diffuse type. The pathological type of the tumor is generally grade I-IV astrocytoma of different grades, and the tumor type is primitive neuroectodermal tumor.

If the tumor boundary is clear, there is a dense tumor astrocytes between the tumor body and the peripheral brain stem nerve tissue, this situation belongs to the expansion type, the pathological type of the tumor is grade I hair cell astrocytoma, the lower part of the brain stem is generally glioblastoma.

matters needing attention

Note: if the tumor seems to have a boundary by naked eyes, but in fact, the tumor cells have invaded into the surrounding brain stem nerve tissue, and the nerve tissue has been completely destroyed by the tumor cells, this situation belongs to invasive tumor, and the above are some causes of brain stem tumor.
