Case report: MRI appearances of left sided Morgagni hernia containing liver.

Morgagni hernias most commonly present in infancy or childhood with gastrointestinal or respiratory symptoms, resulting from visceral herniation into the thorax. They are much rarer in the adult, and may be misdiagnosed as pericardial masses. We report a case of a Morgagni hernia containing liver, which hindered cardiac imaging with echocardiography and angiography, and was best demonstrated with MRI.
