De Garengeot Hernia: A Rare Cause of Acute Abdomen

De Garengeot hernia is a femoral hernia with an appendix vermiformis within the hernia sac. It is named after a French surgeon Rene Jacques Croissant de Garengeot, who first described the appendix in the femoral hernia sac in the 18th century. De Garengeot hernia is a relatively rare clinical entity and only a few surgeons are aware of it. This case described an older female patient, who presented to the emergency department with an incarcerated right sided femoral hernia, which could not be reduced. An emergency surgery revealed incarcerated appendix vermiformis inside the femoral hernia sac – the so called »De Garengeot hernia«.
