What is hemangioblastoma of the brain?
Hemangioblastomas are benign tumors that arise from the linings of blood vessels. Hemangioblastomas can form in the brain, spinal cord, and retina (back of the eye).
What is hemangioblastoma associated with?
INTRODUCTION. Hemangioblastomas are uncommon, slow-growing tumors of the central nervous system, which most commonly occur in the cerebellum, brainstem, or spinal cord. They account for approximately 4 percent of all spinal cord tumors, and 7 to 10 percent of tumors arising in the posterior fossa in adults.
What is spinal hemangioblastoma?
A hemangioblastoma is a benign vascular tumor located along the spine. Although these tumors are benign, they can cause significant neurological problems, depending on their location. Hemangioblastomas are rare, accounting for only three percent of all spinal tumors.
What is the difference between a hemangioma and a hemangioblastoma?
A hemangioma is an abnormal buildup of blood vessels in the skin or internal organs. Two types of hemangiomas are discussed here: Hemangioblastoma: These tumors are benign, slow-growing, and well defined. They arise from cells in the linings of blood vessels.
How fast do hemangioblastomas grow?
Hemangioblastomas grew in a stuttering pattern. (mean growth period 13 +/- 15 months, mean quiescent period 25 +/- 19 months).
Do hemangioblastomas recur?
Most hemangioblastomas have no known cause. However, once surgically or radiologically removed, they generally do not reoccur.
How common are hemangioblastomas?
It affects 1 in 36,000 people. Hemangioblastomas are usually single tumors. Multiple tumors can appear.
Where are hemangioblastomas found?
Hemangioblastoma is a rare form of benign vascular tumor of the CNS, accounting for 2.0% of CNS tumors. It can occur sporadically or as a familial syndrome. CNS hemangioblastomas are typically located in the posterior fossa and the spinal cord.
What is Von Hippel-Lindau disease?
Von Hippel-Lindau disease (VHL) is a rare disease that causes tumors and cysts to grow in your body. They can grow in your brain and spinal cord, kidneys, pancreas, adrenal glands, and reproductive tract. The tumors are usually benign (non-cancerous).
