Primary CNS lymphoma

on 19.1.09 with 0 comments



  • Only 1% of intracranial tumors and 2% of extranodal lymphomas

  • Strongly associated with AIDS and EBV

  • Most are large, high-grade B cell lymphomas and are multiple (astrocytomas are usually solitary)

  • Very aggressive and have a poor prognosis

  • Lymphocytes tend to be in a perivascular location like seen with viral encephalitis
