Hemangioblastoma Sólido de Cerebelo. Presentación de un Caso y Revisión de la Literatura.

Hemangioblastoma is an uncommon benign and highly vascular tumor that is usually observed in the brain, spinal cord and retina. It may be solid or cystic and approximately 25 to 40% of them are associated with von Hippel-Lindau syndrome. Clinical manifestations of hemangioblastoma are nonspecific and they depend on the location and growth pattern of the tumor. Despite its great vascularity, they rarely manifest themselves with hemorrhage and when they do, intraparenchymal bleeding, intramedullary hemorrhage or subarachnoid hemorrhage may be observed. The definitive diagnosis of HB is the pathologic exam. The treatment of choice for hemangioblastoma is microneurosurgery in order to make a complete resection. Preoperative endovascular embolization of feeding vessels may be useful in selected cases as the main risk of this surgery is intraoperative bleeding. We present a case of a 25 years old female diagnosed with right cerebellar hemisphere hemangioblastoma and hydrocephalus, therefore treated through various surgical stages: placing of a medium pressure valve, suboccipital craniectomy, supraselective embolization of feeder vessels and finally extirpation of the tumor mass.
