TY - CHAP M1 - Book, Section TI - Chapter 65. The Central Nervous System: IV. Neoplasms A1 - Chandrasoma, Parakrama A1 - Taylor, Clive R. PY - 1998 T2 - Concise Pathology, 3e AB - Intracranial and spinal neoplasms may be primary or metastatic; in most autopsy series, metastatic tumors are more common. Primary intracranial neoplasms number about 13,000 new cases per year in the United States and represent about 2% of deaths from malignant neoplasms. They are the second most common group of neoplasms in children, after leukemia and lymphoma if considered as one group. Taken overall, 65% of primary intracranial neoplasms are of glial origin (gliomas), 10% meningiomas, 10% acoustic schwannomas, 5% medulloblastomas, and 10% others. Primary malignant lymphomas of the central nervous system have recently increased in frequency because they are common in patients with acquired immunodeficiency disease (AIDS). Tumors of neurons per se are extremely uncommon except in childhood (eg, medulloblastoma).
