[Injuries of the cervical spine and spinal cord in patients with ankylosing spondylitis--diagnosis using magnetic resonance imaging].

Magnetic resonance (MR) imaging results in 8 from 14 ankylosing spondylitis patients treated of traumatic cervical spine and spinal cord injuries are presented. Focal changes within spinal cord were most common among complications (62%), epidural hematoma was found in 50% of cases. Neurological status has worsened in patients with post-traumatic spinal cord pathology.
