Life-threatening vomiting caused by large Morgagni hernia in an octogenarian.

An 84-year-old woman presented with frequent severe vomiting, dyspnea and generalized muscle weakness associated with diaphragmatic hernia. Her poor general condition and muscle weakness resembling cranial pathology were considered to be due to severe vomiting caused by a Morgagni hernia. An urgent subcostal laparotomy confirmed the diagnosis. The critical role of urgent surgery, even in advanced age, is emphasized.
