Unusual Suspect: Ménétrier Disease Presents as Gastric Outlet Obstruction in a Toddler

Ménétrier disease (MD) is a rare condition characterized by hypertrophic gastropathy, leading to enlarged gastric folds, excessive mucus production, and protein loss. Among the approximately 150 cases of reported pediatric MD, the usual presenting features are peripheral oedema, anasarca, and gastrointestinal symptoms. This case report describes a 2-year-old child presenting with gastric outlet obstruction, an unusual manifestation of MD, which has not been described previously in the pediatric age group.
