Overview
Ultrasonography demonstrates the thickened prepyloric antrum bridging the duodenal bulb and distended stomach and it is the modality of choice for the diagnosis of infantile pyloric stenosis.
Ultrasound
Ultrasonography is the modality of choice for the diagnosis of infantile pyloric stenosis.[1]
- The thickened pre-pyloric antrum bridging the duodenal bulb and distended stomach could be seen in the ultrasound of patients with infantile pyloric stenosis.[2]
- Demonstration of the pylorus is achieved by identifying the duodenal cap, distended stomach, and intervening pyloric channel.
- In patients with pyloric stenosis, the following findings may be observed on ultrasonography:
- Variable hypertrophy of the smooth muscle
- Intervening mucosa is crowded, thickened to a variable degree, and protrudes into the distended portion of the antrum nipple sign[3]
- Protruded mucosa may be seen filling the lumen on transverse sections.
- The target sign of infantile pyloric stenosis is a sign seen due to hypertrophied hypoechoic muscle surrounding echogenic mucosa.[4]
