Aortic pseudocoarctation is a congenital abnormality consisting of an elongated aortic arch with a kink at level of the isthmus. However, unlike coarctation, significant flow obstruction is not associated with pseudocoarctation, although there is an increased incidence other cardiovascular anomalies. This case demonstrates the use of multidetector CT as part of the clinical evaluation of a 49-year-old male with suspected aortic coarctation, leading to the final diagnosis of pseudocoarctation, as well as the incidental discovery of a crossed fused ectopic kidney.
主动脉假性缩窄是一种先天性异常，表现为主动脉弓延长并在峡部处形成折角。然而，与缩窄不同的是，假性缩窄并不伴有明显的血流阻塞，尽管其并发其他心血管异常的发生率较高。本病例介绍了多排螺旋 CT 作为临床评估怀疑主动脉缩窄的 49 岁男性的一部分，最终诊断为假性缩窄，并意外发现了交叉融合异位肾。
