Congenital diaphragmatic hernia usually presents with cyanotic attacks, dyspnoea and dextrocardia, a typical triad which is almost considered pathognomonic. The case records of 10 patients (out of a total of 20) of congenital diaphragmatic hernia presenting beyond the neonatal period were reviewed retrospectively. Age and symptoms at presentation and signs elicited were paid special attention. All the patients underwent operative repair of hernia under general anaesthesia. Given below is an explanation for such a high incidence of late presentation in our series. This nomenclature (Congenital Diaphragmatic Hernia "Occulta") will help clinicians in remembering this entity if and when such patients present to the clinicians.
