A 6-week-old infant is admitted with suspected pyloric stenosis. Which finding is characteristic of the infant with pyloric stenosis?
Correct answer
B

Pyloric stenosis presents with a palpable, olive-shaped mass in the epigastrium due to pyloric muscle hypertrophy. Colicky pain is nonspecific, currant jelly stools suggest intussusception, and grain intolerance indicates celiac disease.
