Two infants with recurrent episodes of vomiting had upper gastrointestinal barium studies that did not show radiographic features of pyloric stenosis. However, follow-up abdominal sonograms done 1-2 weeks later documented hypertrophic pyloric stenosis, which led to surgery. This entity is not congenital, but an evolving acquired lesion. Therefore, ultrasound is an excellent modality to evaluate and monitor patients clinically suspected of developing hypertrophic pyloric stenosis despite their initially negative imaging studies.
两名反复出现呕吐症状的婴儿接受了上消化道钡餐检查，未显示出幽门狭窄的影像学特征。然而，1 - 2周后进行的腹部超声随访检查记录到了肥厚性幽门狭窄，这导致了手术治疗。这种情况并非先天性的，而是一种逐渐发展的后天性病变。因此，尽管最初的影像学检查结果为阴性，但超声仍是评估和监测临床怀疑患有肥厚性幽门狭窄患者的极佳方式。
