An anatomic and embryologic study of congenital absence of the pericardium and the relationship of the ligamentum arteriosum to this defect was carried out by the authors. A case report is presented to clinically correlate the anatomic and radiologic findings in this anomaly. The authors propose that visualization of the ligamentum arteriosum by computed tomography is a characteristic sign for congenital absence of the left pericardium.
作者对先天性心包缺如以及动脉韧带与该缺陷的关系进行了一项解剖学和胚胎学研究。现报告一例病例，以将该异常情况的解剖学和放射学表现进行临床关联。作者提出，通过计算机断层扫描显示动脉韧带是先天性左心包缺如的一个特征性征象。
