[edit] Discussion of Hemangioblastoma

  • Hemangioblastomas are benign vascular tumors representing 2% of primary tumors of the CNS.
  • They are most frequently seen in patients between 35 and 45 years of age.
  • Hemangioblastomas are usually isolated tumors but they can also be associated with von Hippel–Lindau disease.
  • Hemangioblastomas in von Hippel–Lindau disease occur in younger patients and have a worse prognosis than do sporadic hemangioblastomas.
  • Hemangioblastomas most frequently affect the cerebellum, followed by the spinal cord and the brainstem.


[edit] Imaging Findings for Hemangioblastoma

  • Cerebral hemangioblastomas are commonly seen at MR imaging as cystic lesion with a solid enhancing mural nodule. The solid nodule give low signal on diffusion weighted imaging (DWI) with resultant increase in the apparent diffusion coefficient (ADC).
