De Garengeot's hernia is a rare condition defined by the herniation of the vermiform appendix within a femoral hernia sac. We report a case of an 80-year-old woman admitted to our emergency department complaining of pain in the right groin. This symptomatology, present for 2 days, increased in the following 12 h. Ultrasonography (US) and contrast-enhanced computed tomography (CECT) were performed, which showed the herniation of the vermiform appendix in the femoral hernia sac. Doppler ultrasonography (DUS) and CECT were the fundamental imaging investigations for this diagnosis. The management of De Garengeot's hernia is surgical through herniorrhaphy, which makes it possible to repair the femoral hernia and perform an appendicectomy in case of appendicitis.
