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).
