Definitions related to hemangioblastoma:
-
A benign tumor of the nervous system that may occur sporadically or in association with VON HIPPEL-LINDAU DISEASE. It accounts for approximately 2% of intracranial tumors, arising most frequently in the cerebellar hemispheres and vermis. Histologically, the tumors are composed of multiple capillary and sinusoidal channels lined with endothelial cells and clusters of lipid-laden pseudoxanthoma cells. Usually solitary, these tumors can be multiple and may also occur in the brain stem, spinal cord, retina, and supratentorial compartment. Cerebellar hemangioblastomas usually present in the third decade with INTRACRANIAL HYPERTENSION, and ataxia.

A hemangioblastoma is a benign vascular neoplasm that arises almost exclusively in the central nervous system. Hemangioblastomas consist of a tightly packed cluster of small blood vessels forming a mass of up to 1 or 2 cm in diameter.Human Phenotype Ontology (HPO)The Human Phenotype Ontology Project, 2021
-
A WHO grade I tumor of uncertain histogenesis which is composed of stromal cells and abundant capillaries. Approximately 25% of hemangioblastomas are associated with Von Hippel-Lindau disease, a disease inherited through an autosomal dominant trait and characterized by the development of hemangioblastomas of the central nervous system and retina, clear cell renal carcinoma, pheochromocytoma, and pancreatic and inner ear tumors.

In 1928, Cushing and Bailey introduced the term hemangioblastoma. It refers to a benign vascular neoplasm that arises almost exclusively in the central nervous system.WebMD, 2019
-
A hemangioblastoma is a benign, highly vascular tumor that can occur in the brain, spinal cord, and retina (the light-sensitive tissue that lines the back of the eye). This tumor accounts for about 2% of brain tumors. As it enlarges, it presses on the brain and can cause neurological symptoms, such as headaches, weakness, sensory loss,...National Center for Advancing Translational Sciences
