title: [Case of surgical treatment for giant hemangioblastoma in the dorsal medulla oblongata].
abstract: Hemangioblastoma in the medulla oblongata is a relatively rare tumor. We present the case of a giant hemangioblastoma occurring in the dorsal medulla oblongata. A 33-year-old man with no neurological symptoms was diagnosed with a hemangioblastoma in the dorsal medulla oblongata, and opted for observation in the outpatient department. After 22 months of observation time, MRI scans showed rapid local tumor progression and obstructive hydrocephalus. At this point, he presented with mild dysphagia as a preoperative neurological deficit. Total surgical removal of the tumor was performed after temporary ventricle drainage and preoperative embolization of the feeding artery. Postoperatively, he became fully conscious but developed bulbar palsy followed by tracheostomy. During the 12 months of postoperative follow-up, severe dysphagia was still present.
