title: Radiographic features of cauda equina syndrome complicating ankylosing spondylitis.
abstract: Cauda equina syndrome is an uncommon complication of ankylosing spondylitis. The characteristics of this disease, as shown by plain radiography, computed tomography and magnetic resonance imaging (MRI) in a 56-year-old man, are described. The MRI features are pathognomonic, allowing accurate noninvasive diagnosis of the disorder.
