Question

A 16 day-old male presents in the office with a history of vomiting after feeding for the past 2 days. The vomiting has become progressively worse and the mother describes it as very forceful, sometimes hitting the floor 6 feet away. She says the neonate is always hungry. On physical examination, it is noted that he is 2 ounces below birth weight, and has a small palpable mass (about 1.5 cm) in the epigastrium. The most likely diagnosis is A. Achalasia. B. Tracheoesophageal fistula. C. Pyloric stenosis. D. Meckel's diverticulum.

Answer 1

The most likely diagnosis in this case is pyloric stenosis.

Achalasia and tracheoesophageal fistula are not relevant to this patient's symptoms, and Meckels's diverticulum would be unlikely to present with such forceful vomiting. So the most likely diagnosis is pyloric stenosis.
