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.
