Hemangioblastoma

Hemangioblastoma is a rare, noncancerous, slow-growing tumor of the brain and spinal cord. It is composed of cells called hemangioblasts, which are the precursors of blood vessels, and is typically found in the cerebellum and the brainstem. The tumors can cause neurological deficits such as seizures, headaches, and balance problems. Because of its location, surgery is usually the only treatment option, and radiation may be necessary as well. Hemangioblastomas have been linked to increased risk of other tumors, including renal cell carcinoma, retinal and ovarian cysts, and pheochromocytomas. Early detection and treatment are key to successful management of hemangioblastomas.
