A rare adult morgagni hernia mimicking lobar pneumonia.

Morgagni hernia is the rarest form of congenital diaphragmatic hernia and is commonly found either in the first few hours of life or in the antenatal period. It is less common in adults and is mostly diagnosed accidentally in asymptomatic patients. Symptomatic adult cases are even rarer with a wide variety of symptoms. We report a patient with a 1-year history of chronic recurrent cough and dyspnea who had been misdiagnosed with recurrent pneumonia before being recognized and treated for Morgagni hernia.
