The pylorus is hypertrophied, measuring about 2 cm in length, associated with increased pyloric muscle thickness. Single muscle wall thickness is 0.5 cm and the whole pyloric thickness is 1.3 cm.
Case Discussion
Hypertrophic pyloric stenosis represents a form of gastric outlet obstruction due to thickening of the muscular layer and failure of relaxation of the pyloric canal. The patient presents with vomiting usually between 2-6 weeks of life. Ultrasonography is the preferred modality of imaging.
