Amyand hernia

Amyand hernia is a rare form of an inguinal hernia in which the vermiform appendix is located within the hernial sac. It is seen in less than 1% of inguinal hernia.

It should not be confused with an appendix-containing femoral hernia, known as De Garengeot hernia.

Clinically, atypical presentation of acute appendicitis is expected, and the clinical presentation may mimic incarcerated inguinal hernia.

  • blind-ending tubular structure arising from caecum and extending into inguinal sac
  • dilated lumen, wall enhancement and thickening, peri-appendiceal fat stranding are suggestive of acute appendicitis
  • extension of the appendix into the inguinal sac
  • if acutely inflamed, the appendix is dilated, non-compressible, thickened and hypervascular

Claudius Amyand, was 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.
