Hemangioblastoma Classification
They can appear sporadic or multiple hemangioblastomas as part of von Hippel-Lindau disease.
Although they can occur in any section of the central nervous system, they usually occur in either side of the cerebellum, the brain stem, or the spinal cord.
These tumors are almost exclusively found in the central nervous system, but in extremely rare cases, it can arise in peripheral nerves.
