Regression of intervertebral disc calcification combined with ossification of the posterior longitudinal ligament:A case report

摘要

BACKGROUND Intervertebral disc calcification(IDC)combined with ossification of the posterior longitudinal ligament(OPLL)in cervical discs is rarely reported.This case study presents a rare case of IDC combined with OPLL in the C2-C3 segment.CASE SUMMARY Here,we present a case of a 6-year-old Asian boy with severe neck pain and stiffness.Physical examination showed no neurological or other abnormalities.Digital radiography and computed tomography(CT)revealed a calcified intervertebral disc and OPLL at the C2-C3 vertebrae.The spinal canal compromise at C2-C3 was approximately 50%on magnetic resonance imaging.The final diagnosis was IDC combined with OPLL.We applied a neck brace for the patient to protect the neck.The patient''s neck pain and stiffness recovered significantly within approximately 3 wk.At the 3 mo follow-up,the follow-up CT showed resolution of the ossified intervertebral disc herniation,and a small amount of calcification and slight OPLL remained at the involved segment.CONCLUSION IDC combined with OPLL is a relatively rare condition in children.However,the majority of patients could have a favorable outcome,and the ossified mass in the canal would be spontaneously resolved with conservative therapy.
