[Non-specific spondylitis in childhood]. / Espondilitis no específica infantil.

Non pyogenic discitis is a benign disease of the pediatric age grup. 1st diagnosis is difficult, as the initial symtons may divert the physician to different organs or systems other than the spine. Establishing the diagnosis in the early stage of the disease is important in order to avoid unnecessary and expensive diagnostic procedures. Non pyogenic discitis is diagnosed on radiograms by the demonstration of the narrow disc-space with involvement of the adjacent vertebral bodies. Four phases are recognised in the development of the imaging changes.
