Unusual Presentation of Acute Appendicitis: A Case Report of de Garengeot Hernia.

A de Garengeot hernia (DGH) is a rare anatomic variant involving the herniation of the appendix through the femoral canal. It is an uncommon surgical entity with diagnostic challenges. We report the case of a 63-year-old woman who presented with right inguinal region pain and swelling, in which preoperative ultrasound (US) and computed tomography (CT) identified the herniated, inflamed appendix within the canal of Nuck, which was intraoperatively found to be rather a femoral hernia. This rare case illustrates the characteristic imaging features of DGH and highlights the importance of early and accurate radiologic diagnosis for surgical planning and improved patient outcomes.
