Summary
Hemangioblastomas are vascular brain tumors mainly localized to the cerebellum. We typically find them in adults, as well as children who have Von Hippel-Lindau Syndrome. The presence of hemangioblastomas can cause an increase in the hormone erythropoietin, which often leads to secondary polycythemia. A biopsy will reveal a highly vascular tumor with a foam-like appearance.
