Posterior cranial fossa tumor

Posterior cranial fossa tumors include gliomas, meningiomas, or medulloblastomas.

1. Glioma: It is usually caused by genetic factors or electromagnetic radiation. Long-term use of mobile phones may increase the incidence of brain glioma. It may also be due to viral infection, such as macrophage virus infection. It also has a certain relationship with age factors. Glioma is usually seen in people between 60 and 80 years old. Symptoms vary depending on the size, location, and growth rate of the tumor, but usually include nausea and vomiting, with seizures and blurred vision.

2. Meningioma: It is usually caused by a variety of factors that lead to genetic mutations in arachnoid cells, or changes in environmental factors that lead to uncontrolled division and proliferation of arachnoid cells. Estrogen level disorders in the body, or a family history of meningioma and breast cancer can usually cause the occurrence of meningioma. A history of breast cancer often also causes meningioma.

3. Medulloblastoma: It usually originates from the progenitor cells of cerebellar granule neurons. For some reason, the progenitor cells undergo genetic mutations and usually proliferate uncontrollably, which may lead to medulloblastoma. The disease may cause cerebrospinal fluid circulation disorders, and hydrocephalus may also lead to increased intracranial pressure.
