[Congenital posterolateral diaphragmatic hernia with delayed clinical manifestations (author's transl)].

Two cases of late-appearing congenital posterolateral diaphragmatic hernia are described. Chest X-rays performed a few hours after birth were normal. The diagnosis was made 45 days and 18 months after birth. Authors call attention about this unusual presentation of Bochdalek hernia. A review of the literature is made.
