The pyloric canal is elongated with thick muscular wall giving the cervix sign and antral nipple sign.
Case Discussion
The most accurate ultrasound measurement is the single muscular wall thickness being more than 3 mm, in this patient the single wall thickness was at least 6 mm.
Positive cases will not show feeds passing through the pylorus. A degree of pylorospasm is common in infancy and is responsible for some delay in gastric emptying. The pylorus, however, appears sonographically normal.
The treatment is pyloroplasty.
