Although proatlas segmentation abnormalities as developmental remnants around the foramen magnum have been reported in postmortem studies, they are rarely documented in a clinical setting. This report details the clinical and radiological characteristics of a rare case of proatlas segmentation abnormalities with clinical onset during the seventh decade of life. This case was suspected to have a familial factor. We also review the literature regarding this condition.
尽管在尸检研究中已报告枕骨大孔周围作为发育残留的原寰椎分割异常,但在临床环境中很少有记录。本报告详细介绍了一例罕见的原寰椎分割异常病例的临床和放射学特征,该病例在70岁时出现临床症状。该病例疑似存在家族因素。我们还回顾了关于这种情况的文献。
