Abstract
A 52-year-old female patient was admitted to our hospital with severe occipitocervical pain. The radiographic examination revealed degenerative osteoarthritis and subluxation of the right atlantoaxial joint. Her pain was completely and immediately relieved after occipitocervical reduction and fusion. The marked dilatation of the extradural venous plexus around the vertebral artery and the enlarged deep cervical veins seen on the preoperative MR images had returned to normal dimensions on the postoperative MR images, and this explained the observed rapid pain relief. We report here on this case together with a review of the relevant literature.
