Cholecystolithiasis mimicking pyloric stenosis

Causes of persistent vomiting in an otherwise healthy neonate or young infant include faulty feeding, aerophagia, congenital pyloric stenosis, severe gastro-esophageal reflux disease or upper gastrointestinal obstruction1-4. The advice of correct feeding technique and proper burping after feeding usually resolves the minor ailment. Projectile non-bilious vomiting and upper abdominal distension with a palpable mass suggest the diagnosis of congenital hypertrophic pyloric stenosis (CHPS). Ultrasonography further confirms the diagnosis. Authors report a one-month-old infant who was referred as a case of CHPS because of persistent severe vomiting, abdominal distension and poor feeding. The abdominal ultrasonography findings revealed an entirely different rare entity, cholecystolithiasis. The treatment, course in the hospital and follow up of the case is discussed.
