Discussion

Morgagni's hernia is the least common of all congenital diaphragmatic hernias, with an incidence of 3% ¹. As in this case, it may be associated with Down's syndrome, Turner's syndrome, dextrocardia, Prader-Willi syndrome and tetralogy of Fallot, among others. It is usually an incidental finding in adults and when clinical manifestations are present, these are often nonspecific, although cases with gastric outlet obstruction, respiratory distress or intestinal ischemia have been reported. The imaging technique of choice for the diagnosis of Morgagni's hernia is thoracoabdominal CT ². Treatment usually consists of surgery with laparotomy but a mixed thoracic and abdominal approach may also be used ³. Furthermore, a case repaired using minimally invasive robotic surgery was recently reported ⁴.
