Delayed presentation of congenital diaphragmatic hernia.

Eight patients aged 1 month up to nine years with congenital diaphragmatic hernias (seven left sided postero-lateral, one right-sided antero-medial), who presented outside of the neonatal period, are reported, four are described in detail. Radiographic presentation was obvious in four patients, simulated inflammatory lung disease in one and pneumothorax in two. In one patient a Morgagni hernia was primarily missed. Two had previous normal chest X-rays. All cases with herniated bowel showed "connecting" bowel segments passing through the diaphragmatic defect. Primarily the lack of awareness of delayed presentation of congenital diaphragmatic hernia in children with uncharacteristic thoracic and/or abdominal symptoms led to an undesirable time delay between first chest X-ray and surgery up to 16 months in four of our cases. Life threatening complications can be the consequence of delayed diagnosis as in one of our cases.
