Appendicitis within a femoral hernia: Sonographic appearance

Appendix within a femoral hernia was first described by the Parisian surgeon Rene Jacques Croissant de Garengeot in 1731 and is a rare, often incidental finding at surgery. Appendicitis in a femoral hernia is even more rare, and although it has been well reviewed in the medical literature, its sonographic appearance has been described only once. We report the sonographic findings of appendicitis in a femoral hernia and stress the potential benefits of this imaging modality in cases of acute groin pain and swelling.
