Some tumors may not show symptoms until they are very large and cause rapid neurologic decline, others are characterized by slowly progressive symptoms. Angiography of the head shows a space-occupying mass, which may or may not be highly vascular. Examination of tissue removed from the tumor during surgery or CT scan-guided biopsy is used to confirm the exact type of tumor. This disease may also alter the results of a CPK isoenzymes test. A primary brain tumor should have prompt treatment.
Early treatment improves the chance of a good outcome for many tumors.
Treatment varies with the size and type of the tumor and the general health of the person. The goals of treatment may be cure of the disorder, relief of symptoms and improvement of function, or comfort. Surgery is indicated for most primary brain tumors. Surgery may reduce intracranial pressure and relieve symptoms in cases when the tumor cannot be removed. Radiation therapy may be advised for tumors that are sensitive to this treatment.
