title: Intervertebral disc calcification in children: Case description and review of relevant literature.
abstract: BACKGROUND
  Intervertebral disc calcification is a rare condition in children; in most cases, it is asymptomatic and therefore not diagnosed.
  
  
  METHODS
  In our study, we present a case of idiopathic intervertebral disc calcification within the cervical segment, at the level of C2/C3 and C4/C5 vertebrae in a 5-year-old girl with torticollis. Basic neurological examination supplemented by X-ray examination was performed, showing calcification within the cervical segment at the level of C2/C3 and C4/C5 vertebrae.
  
  
  CONCLUSIONS
  In order to complement the diagnostics, a CT scan of the cervical spine was performed; the scan confirmed the diagnosis and revealed additional calcification of the anterior longitudinal ligament at the level of C4/C5 vertebrae.
