At least 25,000 of these tumors are malignant, and most of these are gliomas. Meningiomas account for 35%, vestibular schwannomas 10%, and central nervous system (CNS) lymphomas ~2%. Brain metastases are three times more common than all primary brain tumors combined and are diagnosed in ~150,000 people each year. Metastases to the leptomeninges and epidural space of the spinal cord each occur in ~3–5% of patients with systemic cancer and are also a major cause of neurologic disability.
