Congenital diaphragmatic hernias, including Morgagni s hernia, usually present in early childhood and are treated by surgical repair. This case report is about an unusual Morgagni s hernia, presenting with dyspepsia and chest pain, at the age of 45 years. For many years the diagnosis remained a dilemma because patient s chest x-ray was not done and she was treated for "angina " and "dyspepsia". Diagnosis was obvious once a chest x-ray was done, however, barium studies were performed for further confirmation.
