An Amyand hernia describes a inguinal hernia containly the appendix, without any other intraperitoneal contents.

In this, as most cases, it is an incidental finding.

It is named after Claudius Amyand, a French surgeon who performed the first successful appendectomy in 1735, on an 11-year-old boy who presented with an inflamed, perforated appendix in his inguinal hernia sac.
