Cerebellar tumors account for 5% to 15% of all brain tumors. Tumors can be both benign and malignant in nature. Benign tumors grow slowly, have clear boundaries and rarely spread. Although the tumor consists of benign cells, it is life-threatening due to the compression of adjacent areas of the brain.
The malignant tumor grows rapidly, has blurred borders and spreads rapidly to neighboring areas of the brain. Although malignant tumors are sometimes called brain cancers, they do not fall under the definition of cancer because they do not spread to organs outside the brain and spinal cord.
Causes of cerebellar tumors
The ultimate causes of tumors have not yet been elucidated, although some genetic changes (eg, mutation in the p53 protein gene) may be a trigger for these tumors. The most common tumors of the cerebellum in adults are hemangioblastoma, astrocytomas of varying degrees of malignancy, medulloblastomas, cancer metastases, ependymomas. By the nature of tumor growth are divided into nodular and infiltrative tumors.
According to the signs of malignancy, tumors are divided into 4 degrees:
I - Cells grow slowly, have an almost normal appearance; associated with long-term survival. II - Relatively slow-growing cells, somewhat abnormal appearance of cells, can spread to neighboring areas, sometimes can become more malignant. III - Active reproduction of abnormal cells, abnormal appearance, penetrate into normal tissue. IV - Rapid reproduction of abnormal cells, very distorted appearance, the area of dead cells (necrosis) in the center, quickly form new blood vessels to support growth, metastasize to the brain and spinal cord.
Cerebellar tumors: symptoms
The most common symptoms are shaky gait, incoordination, headache, nausea, vomiting, mainly in the morning. Also, sometimes there are speech disorders, diplopia or other visual disturbances. The most informative method of confirming the diagnosis is magnetic resonance imaging with intravenous contrast.
The only effective treatment for patients with cerebellar tumors is surgery. Depending on the results of histological examination of the tumor after surgery, surgical treatment is supplemented by radiation and / or chemotherapy.
Our clinic treats more than 150 patients with tumors of the cerebellum and IV ventricle every year.
The use in the clinic of state-of-the-art neurosurgical technologies, anesthesia, such as intraoperative neuromonitoring, operating microscope, microsurgical instruments and microcoagulation, tumor removal by ultrasound aspiration, reduces trauma to the surrounding brain structures. In patients with aggressive tumors, the diagnosis and treatment plan are discussed by physicians in several specialties. The opinions of oncologists, neurosurgeons and neuroradiologists are taken into account. Our specialists are able to control the growth of cerebellar tumors through a combination of treatments, including surgery, chemotherapy, radiosurgery and radiation therapy of all parts of the brain.
You can get a detailed consultation about your disease and answers to all questions in our clinic, which has been specializing in the treatment of this pathology for over 30 years and has the most experience in Ukraine.
