背景动脉韧带钙化可能是某些儿童的正常发现，尽管其频率尚未得到很好的描述。目的在死后成像中估计儿童动脉韧带钙化的频率。材料和方法我们对儿科尸检CT进行了单中心回顾性审查6年内（2012年1月至2018年12月）的胸部X线摄影成像。两名独立的审查员评估了成像上钙化的存在。我们计算动脉韧带钙化的频率和与年龄和gender.ResultsDuring研究期间，220名儿童进行了全身尸检CT和182进行了放射成像的描述性统计分析。尸检CT的频率高于X线平片（67/220，30.5% vs. 3/182，1.6%），1-7岁儿童的频率最高（53.6-66.7%），年龄较大儿童的频率逐渐降低，12岁以上儿童的频率为零。没有性别predilecation.ConclusionIn尸检设置，动脉韧带钙化是一个常见的发现在儿童<8岁。它可以更好地确定在死后的CT比胸部X光片。刚开始报告尸检儿科CT研究的放射科医生应认识到这是一种常见的正常发现，以避免尸检时不必要的进一步调查。
BackgroundLigamentum arteriosum calcification may be a normal finding in some children, although the frequency has not been well described.ObjectiveTo estimate the frequency of ligamentum arteriosum calcification in children at postmortem imaging.Materials and methodsWe conducted a single-centre retrospective review of paediatric postmortem CT and chest radiographic imaging over a 6-year period (January 2012 to December 2018). Two independent reviewers assessed the presence of calcification on imaging. We calculated descriptive statistical analysis of ligamentum arteriosum calcification frequency and association with age and gender.ResultsDuring the study period, 220 children underwent whole-body postmortem CT and 182 underwent radiographic imaging. The frequency was higher on postmortem CT than plain radiographs (67/220, 30.5% vs. 3/182, 1.6%) and was highest in children ages 1–7 years (53.6–66.7%), with gradual reduction in frequency in older children, and none in children older than 12 years. There was no gender predilection.ConclusionIn the postmortem setting, ligamentum arteriosum calcification is a common finding in children <8 years of age. It can be better identified on postmortem CT than chest radiographs. Radiologists new to reporting postmortem paediatric CT studies should recognise this as a common normal finding to avoid unnecessary further investigations at autopsy.
