Info

Abdominal ultrasound shows an elongated pyloric canal with increased pyloric muscle thickness. Redundant pyloric mucosa is seen projecting into the gastric antrum on longitudinal image (antral nipple).
Case Discussion
Pyloric muscle thickness >3 mm on a transverse image and pyloric canal length >15 mm is compatible with congenital hypertrophic pyloric stenosis 1 which in our case measures 5.8 mm and 17.9 mm, respectively.
