Infantile Hypertrophic Pyloric Stenosis in an Infant with Tetralogy of Fallot: Association or Coincidence?

Abstract

Infantile hypertrophic pyloric stenosis is an important cause of vomiting in apparently healthy infants, typically between 2-8 weeks of life. It mostly occurs as an isolated abnormality but there are cases reported to be associated with congenital anomalies. We report a case in a 2-months-old infant who presented with non-bilious vomiting associated with feeding for 15 days. He was already diagnosed to have pink Tetralogy of Fallot. He was diagnosed as a case of hypertrophic pyloric stenosis on the basis of ultrasonography and barium studies, and underwent pyloromyotomy. Post-operative recovery was uneventful and he has no associated complications on follow-up.
