Case Discussion

The patient presented with several days of right upper quadrant pain. CT shows findings of acute cholecystitis. Incidental note of bilateral inguinal hernias, with the appendix within the right inguinal hernia (Amyand hernia).

Amyand hernia is defined as a hernia containing the appendix, most often an inguinal hernia. It constitutes about 1% of all hernias. Rarely, it may be complicated by concomitant appendicitis. It is most often discovered as an incidental finding through imaging or at the time of surgery. It is named after French surgeon Claudius Amyand, who on December 6, 1735, performed the first successful appendectomy on an 11-year-old boy with a right inguinal hernia containing the appendix.
