颈胸椎弥漫性特发性骨肥厚症合并后纵韧带骨化症1例报告

Cervical-Thoracic Vertebral Diffuse Idiopathic Skeletal Hyperostosis Combined with Ossification of the Posterior Longitudinal Ligament:One Case Report

弥漫性特发性骨肥厚症(diffuse idiopathic skeletal hyperostosis,DISH)是中老年人常见骨骼疾病,主要累及脊柱,特征是大量表浅的不规则椎体前和侧缘骨质增生相互融合形成椎体前广泛肥厚骨块,又称强直性骨肥厚[1-2]或Forestier病。该病多累及脊柱前外侧韧带,尤以颈椎、上胸椎多节段前纵韧带骨化为特征性表现,其中约1/4的患者合并后纵韧带骨化症(ossification of the posterior longitudinal ligament,OPLL),发生脊髓压迫症状者少见。
