We describe a case of late post-traumatic diaphragmatic hernia revealed during pregnancy by bowel obstruction. The diagnosis was made during exploratory laparotomy at 29 weeks. After surgical repair of the hernia the pregnancy went to term uneventfully. A healthy baby was delivered at 39 weeks by elective cesarean section.
