Chest radiographs and ultrasound images in representative patients with diaphragmatic hernia (upper panels) and diaphragmatic eventration (lower panels). (Upper panels) A 5-month-old boy, with right Bochdalek hernia. Anteroposterior and lateral chest radiographs demonstrate what would appear as global elevation of the right hemidiaphragm (a, b). Lateral long-view ultrasound (c) demonstrates the normal anterior hypoechogenic muscle (arrowheads), the folding free edge of the diaphragm at a narrow angle waist (arrow), and the herniated liver through the diaphragmatic defect (H). (Lower panels) A 9-month-old boy, with right diaphragmatic eventration. Anteroposterior and lateral chest radiographs demonstrate global elevation of the right hemidiaphragm (a, b). Long-view ultrasound (c) demonstrates posterior elevation of the diaphragm with a wide-angle waist. The normal anterior hypoechogenic diaphragm (arrowheads) with focal thickening of the muscle (arrow) covering the entire waist.
