Hemangioblastoma. A 40-year-old male with neck spasms and gait disturbance. a and b Spinal cord syrinx involving the entirety of the cervical cord extends superiorly to the cervicomedullary junction, where there is mass effect on the brainstem with resulting edema (arrow); therefore, more inferior spine imaging was obtained to look for the cause. c Sagittal T2 image shows an intramedullary lesion within the lower thoracic cord with associated syrinx (arrow). Serpiginous flow voids (arrowhead) are feeding vessels. d T1 post-contrast fat-saturated image demonstrates a nodule of homogeneous enhancement
