目的探讨儿童椎间盘钙化病的临床特点及X线、CT、MR影像学特征及其演变过程。方法报道儿童颈椎间盘钙化病6例,均拍摄颈椎正侧位X线平片及CT,2例行MR检查,并对全部病例进行2~3年CT、X线追踪观察。结果6例患儿均为单椎间盘发病,X线、CT表现为椎间盘钙化,髓核脱出,伴有椎体形态改变。经对症治疗,2~4周内症状均消失,钙化则在6个月~3年内消失。结论儿童椎间盘钙化病是一种自限性疾病,影像学是主要诊断方法。
Objective To investigate the clinical features and radiographic characteristics of X-ray, CT and MR in children with intervertebral disc calcification and its evolution. Methods Six cases of cervical intervertebral disc calcification were reported in children. X-ray plain films and CT were taken from the cervical spine. MR imaging was performed in 2 cases. All the cases were followed up for 2 to 3 years by CT and X-ray. Results All 6 cases were single disc disease. X-ray and CT showed intervertebral disc calcification and nucleus pulposus prolapse with the change of vertebral body shape. After symptomatic treatment, 2 to 4 weeks the symptoms disappeared, calcification in 6 months to 3 years disappear. Conclusion Calcified disc disease in children is a self-limited disease, imaging is the main diagnostic method.
