• 10% multiple
• erythrocytemia in 20%

• age:
  • adulthood: average age of 33; M>F
  • childhood: von Hippel Lindau (10%); F>M

• location: cerebellum > spinal cord > cerebrum

• findings:
  • cystic mass (2/3); solid tumor (1/3)
  • homogenous enhancement of mural nodule (50%)
  • occasional enhancement of cytic wall
