title: Case report: pseudoarthrosis complicating ankylosing spondylitis--appearances on magnetic imaging.
abstract: Development of typical pseudoarthrosis from an acute fracture in the spine of a patient with ankylosing spondylitis is documented by serial radiographs. The magnetic resonance imaging appearances of pseudoarthrosis are correlated with histological findings of the surgical specimen.
