[Computerized tomography in rheumatoid arthritis of the cranio-cervical junction].
Twenty rheumatoid arthritis (RA) patients with involvement of the cranio-cervical junction (CCJ) were given CT scan. In most cases the myelo-CT technique with the lumbar injection of small quantities of non-ionic contrast medium was adopted; CT easily diagnosed the "horizontal" and "vertical" dislocations on the CCJ, the bone structure lesions and the inflammatory masses. A high frequency of medullary compressions was also found in these patients. Myelo-CT appears to be the technique of choice for the precise definition of the various factors responsible for the neurological complications found in RA of the CCJ.
