Overview
Ultrasonography is the the modality of choice for the diagnosis of infantile pyloric stenosis.The thickened prepyloric antrum bridging the duodenal bulb and distended stomach and crowded intervening mucosa that protrudes into the distended portion of the antrum (nipple sign) may be seen in Ultrasonography of patients with infantyle pyloric stenosis.
Diagnostic Study of Choice
Gold standard of choice:
- Ultrasonography is the modality of choice for the diagnosis of infantile pyloric stenosis.[1]
- The following result of ultrasonography is confirmatory of infantile pyloric stenosis:
- Hypertrophied hypoechoic muscle surrounding echogenic mucosa may be seen in the ultrasound of patients with infantile pyloric stenosis called target sign.[3]
