Acute Calcification of Intervertebral Disc and Posterior Longitudinal Ligament in a 7-Year-Old Girl: A Case Report

A 7-year-old girl presented with a 2-day history of acute neck pain without any preceding injury. The pain was around the left posterior paraspinal muscle and was aggravated by neck movement. There was no neurological abnormality; white cell count and inflammatory markers were slightly elevated. Radiology of the cervical spine showed calcification of C3/4 and C4/5 discs as well as the posterior longitudinal ligament over C3/4. She was treated conservatively with a neck collar and Panadol syrup. No non-steroidal anti-inflammatory drug was prescribed. Two months later, calcification of the posterior longitudinal ligament had resolved and calcification at C3/4 and C4/5 discs and the C4 lower endplate had decreased. After one year, she was pain-free with no tenderness over her neck and had full range of neck motion and complete resolution of the calcification.
