title: Spectrum of magnetic resonance imaging findings in congenital lumbar spinal stenosis.
abstract: OBJECTIVE
  To investigate whether congenital lumbar spinal stenosis (CLSS) is associated with a specific degenerative changes of the lumbar spine.
  
  
  METHODS
  The lumbar spine magnetic resonance imaging studies of 52 subjects with CLSS and 48 control subjects were retrospectively evaluated. In each examination, the five lumbar levels were assessed for the presence or absence of circumferential or shallow annular bulges, annular tears, anterior or posterior disc herniations, epidural lipomatosis, Schmorl's nodes, spondylolisthesis, pars defects, and stress reactions of the posterior vertebral elements.
  
  
  RESULTS
  Compared to control individuals, subjects with CLSS exhibited increased incidence of circumferential and shallow annular bulges, annular tears, disc herniations and spondylolisthesis (P < 0.05).
  
  
  CONCLUSIONS
  CLSS is associated with increased incidence of degenerative changes in specific osseous and soft-tissue elements of the lumbar spine.
