Primary lymphoma of the brain

  • Definition
    • Primary lymphoma of the brain is cancer of white blood cells that starts in the brain.

  • Alternative Names
    • Brain lymphoma; Cerebral lymphoma; Primary lymphoma of the central nervous system; Lymphoma - brain

  • Causes
    • The cause of primary brain lymphoma is not known.

      People with a weakened immune system are at high risk for primary lymphoma of the brain. Common causes of a weakened immune system include HIV/AIDS and having had an organ transplant (especially heart transplant).

      Primary lymphoma of the brain may be linked to Epstein-Barr Virus (EBV), especially in people with HIV/AIDS. EBV is the virus that causes mononucleosis.

      Primary brain lymphoma is more common in people ages 45 to 70. The rate of primary brain lymphoma is rising. But this cancer is still very rare.

  • Symptoms
    • Symptoms of primary brain lymphoma may include any of the following:

      • Changes in speech or vision
      • Confusion or hallucinations
      • Fever
      • Headaches or seizures
      • Leaning to 1 side when walking
      • Weakness in hands or loss of coordination
      • Numbness to hot, cold, and pain
      • Personality changes
      • Weight loss
  • Exams and Tests
  • Treatment
  • Outlook (Prognosis)
    • Without treatment, people with primary brain lymphoma survive for less than 2 months. Those treated with chemotherapy often survive 3 to 4 years or more. This depends on whether the tumor stays in remission. Survival may improve with autologous stem cell transplant.

  • Possible Complications
    • Possible complications include:

      • Chemotherapy side effects, including low blood counts
      • Radiation side effects, including confusion, headaches, nervous system (neurologic) problems, and tissue death
      • Return (recurrence) of the lymphoma
