Successful total removal of intramedullary hemangioblastoma from the medulla oblongata

Abstract The case of a large solid hemangioblastoma embedded wholly in the medulla oblongata is reported. Preoperative magnetic resonance imaging provided precise indications of the anatomical location and radiologic features of the tumor, which facilitated its total removal by microsurgery. Short-latency somatosensory evoked potentials were monitored throughout the operation.
