It is said that calcified intervertebral disc was confirmed anatomically by Luschka in 1858, and Benke proved it radiologically with cadaver in 1897. In 1922, calcified nucleus pulposus was found by Calve and Galland, and they named it “calcification du nucleus pulposus”. Then Bársony renamed it “calcification intervertebralis”, because calcification was not seen only in nucleus pulposus but everywhere in the intervertebra. On the other hand, pediatric disc calcification was described by Báron in 1924. Since then, about 200 cases of children have been reported.
In Japan Calcified intervertebral disc is considered rare. In 1932, the cases of a 13-year-old girl and 68-year-old female were described by Mizumachi. Since then, there have been sereval case reports of adults with especially intervertebral thoracial discs, but few reports of children.
This paper reports the case of a 12-year-old boy with a calcified intervertebral disc at C 4-5 discovered by neck pain. With conservative treatment, X-rays 18 months later showed complete resolution of the calcification.
