The occurrence of calcified discs with large calcified masses protruding into the spinal canal in two children is reported. The discs affected had increased height in the acute stage. Air myelogram, performed in one case with muscular weakness in the hand demonstrated compression of the spinal cord. The condition improved on conservative treatment without sequelae in both cases.
