The pylorus shows thickened muscle layer measures about 5.3 mm in thickness, it is also elongated and measures 21 mm in length. This is indicative of hypertrophic pyloric stenosis. A note is made of a Phrygian cap of the gallbladder (normal variant).
Case Discussion
Congenital hypertrophic pyloric stenosis is more common in boys and manifested at 3-8 weeks of life. Its diagnosis can easily be made by ultrasonography and depends on visualization of thickened pyloric muscle layer (> 3 mm) and elongated pyloric canal (> 15 mm).
