Morgagni  hernias  are  often  misdiagnosed  as  a  consolidation  or  collapse of  the  right  middle  lobe,  and  should  be  considered  in  the  differential  diagnosis of  opacification  at  the  right  cardiophrenic  angle. They  are  a  form  of  congenital diaphragmatic  hernia  and  are  best  demonstrated  on  multidetector  computed tomography.  Medical  management  will  help  alleviate  gastrointestinal  symptoms,  but curative management is usually surgical to prevent the complication of strangulation.
