Hypertrophic pyloric stenosis, an unusual presentation and rare association: case report and literature review

Abstract

Hypertrophic pyloric stenosis (HPS) is a commonly encountered surgical condition that occurs in infancy, but not in neonates. This report describes a 10-day-old male patient with atypical presentation of HPS, with an incidental diagnosis of eventration of the left diaphragm. The symptoms were present since birth with nonprojectile, nonbilious vomiting and gastric distension. A contrast study showed a gastric outlet obstruction with the possibility of gastric volvulus. Emergency surgery established the diagnosis. To the best of our knowledge, the association of HPS with diaphragmatic defect and gastric volvulus is rare, and few cases have been reported in the literature.
