title: The MRI findings of a de Garengeot hernia.
abstract: The presence of the appendix within a femoral hernia is rare. It was first described by the French surgeon Jacques Croissant de Garengeot in 1731. This phenomenon accounts for 0.8-1% of all femoral hernias. Acute appendicitis occurring within a femoral hernia is even rarer and is difficult to diagnose pre-operatively. This type of hernia is termed a de Garengeot hernia. The ultrasonographic and CT imaging features of de Garengeot hernias have been described previously. We report a case of a 57-year-old female who presented with a painful right-sided groin mass. She underwent MRI of the inguinal region, which successfully diagnosed this rare hernia pre-operatively. To our knowledge, this is the first description of a de Garengeot hernia diagnosed using MRI.
