A 7-year-old patient was recently treated surgically for a right paraduodenal hernia. Paraduodenal hernia is a rare cause of chronic abdominal complaints, as well as acute obstruction, and although it is not typical, it can manifest in childhood. The term "hernia" is a misnomer since this condition results from anomalous intestinal rotation. Knowledge of this embryology will prevent injury to vital mesenteric vessels during "repair" of a right paraduodenal hernia.
