The most common forms of brain tumor in the elderly are metastasis, glioma, meningioma, pituitary adenoma, and acoustic neuroma. They produce a variety of neurologic symptoms and usually can be readily diagnosed by CT scan. ⋯ The prognosis of a patient with a brain tumor depends on the tumor's histology, its location, and the patient's ability to tolerate therapy. Early diagnosis is important for successful treatment.
