Congenital hypertrophic pyloric stenosis

Case contributed by Dr Kewal Arunkumar Mistry


Infant presented with non bilious vomiting.

Patient Data

Age: 2 months
Gender: Male

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.
