To the best of our knowledge this is the first report of this kind of hernia presenting with signs and symptoms of severe cardiac malformation. Case presentation We report the case of a three-month-old Caucasian baby boy who presented with heart failure and severe pulmonary hypertension. Compression of the heart by a bowel loop in the chest led to an incorrect diagnosis of congenital heart disease. Conclusions Even in this era of highly sophisticated diagnostic tools a simple radiograph can provide sufficient information for a precise rapid diagnosis. Introduction Congenital diaphragmatic hernia CDH is a congenital birth defect involving abnormal development of the diaphragm. The condition is produced by a hole in the diaphragm which allows the abdominal contents to protrude into the chest cavity. Accounting for approximately 2 of all CDH cases Morgagni s CDH is characterized by herniation through the foramina of Morgagni located immediately adjacent to the xiphoid process of the sternum 1 2 . The defect in the diaphragm is generally located on the right side 90 or bilaterally 7 occasionally it may be on the left side although the presence of both heart and pericardium are a barrier against herniation 3 4 . Most patients are asymptomatic until adulthood. The lesion rarely presents during the neonatal period in which case it leads to severe respiratory distress sometimes associated with anomalies in other organs including the heart 5 6 . Diagnosis may prove problematic as we describe in
