A cerebellar tumor accounts for 5% to 15% of cases among all brain tumors. Tumors can be either benign or malignant in nature.
Benign tumors grow slowly, have clear boundaries, and rarely spread to neighboring areas. Although the tumor is composed of benign cells, it is life threatening due to compression of the surrounding areas of the brain.
A malignant tumor of the cerebellum grows rapidly, has indistinct boundaries and quickly spreads to neighboring areas of the brain. Although malignant tumors are sometimes called brain cancer, they do not fall under the definition of cancer because they do not spread to organs outside the brain and spinal cord.
The final causes of the appearance of tumors have not yet been clarified. Although some genetic changes (for example, mutation of the p53 gene) can be a triggering mechanism in the development of these tumors.
Cerebellar tumor in adults
astrocytomas of varying degrees of malignancy
By the nature of growth, tumors are divided into nodal and infiltrative neoplasms.
According to the signs of malignancy, tumors are divided into 4 degrees:
І The cells grow slowly, have an almost normal appearance; associated with long term survival
II Comparatively slow growing cells, somewhat abnormal in appearance, can spread to neighboring areas, sometimes they can turn into more malignant ones.
ІІІ Active reproduction of anaplastic cells, abnormal appearance, penetrate into normal tissue
IV Rapid reproduction of anaplastic cells, very distorted appearance, areas of dead cells (necrosis) in the center, new blood vessels are rapidly formed to support growth, metastasized in the brain and spinal cord
Cerebellar tumor: symptoms
The most common symptoms are:
unsteadiness of gait
lack of coordination of movements
vomiting mainly in the morning
also sometimes there is difficulty in speech, double vision
The most informative method for confirming the diagnosis is magnetic resonance imaging with intravenous contrast.
The only effective treatment for patients with cerebellar tumors is surgical removal of the tumor. Depending on the results of the histological examination of the tumor after surgery, surgical treatment is supplemented by radiation and / or chemotherapy.
Our clinic annually treats more than 150 patients with tumors of the cerebellum and IV ventricle. The use in the clinic of modern neurosurgical technologies, anesthetic support, such as neuromonitoring, an operating microscope, microsurgical instruments and microcoagulation, removal of a tumor by ultrasonic aspiration can reduce trauma to the surrounding brain structures, preserve or improve the quality of life of patients, and increase the radicality of surgical removal of tumors. In patients with aggressive tumors, the diagnosis and treatment plan are discussed by doctors of several specialties with the involvement of oncologists, neurosurgeons and neuroradiologists. Our specialists are able to control the growth of cerebellar tumors through a combination of different therapies, including surgery, chemotherapy, radiosurgery and radiation therapy.
