hemangioblastoma
Hemangioblastomas, or haemangioblastomas, are vascular tumors of the central nervous system that originate from the vascular system, usually during middle age. Sometimes, these tumors occur in other sites such as the spinal cord and retina. They may be associated with other diseases such as polycythemia (increased blood cell count), pancreatic cysts and Von Hippel–Lindau syndrome (VHL syndrome). Hemangioblastomas are most commonly composed of stromal cells in small blood vessels and usually occur in the cerebellum, brainstem or spinal cord. They are classed as grade I tumors under the World He

They are classed as grade I tumors under the World Health Organization's classification system.
==Presentation== ===Complications=== Hemangioblastomas can cause an abnormally high number of red blood cells in the bloodstream due to ectopic production of the hormone erythropoietin as a paraneoplastic syndrome.
