Morgagni hernia association with Bochdalek diaphragmatic hernia is a very rare congenital anomaly.
The authors reported a 2-year-and-2-month-old boy with Down syndrome who has a history of recurrent
pneumonia over a one-year period. A chest film of the first admission at 6 months of age revealed only minimal
pulmonary infiltration and normal findings of both sides of the diaphragm. The last investigations with chest
films and CT scan were suggestive of sequestration of the right lung with left Morgagni and left Bochdalek
diaphragmatic hernias. An exploratory laparotomy revealed bilateral Morgagni and left Bochdalek hernias
with hernial sacs in all of the diaphragmatic defects. All of the hernial sacs were excised and the diaphragmatic
defects were closed with 2-0 silk interruptedly. Postoperative course was uneventful and he was doing well
during his follow-up at one year.
