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
History and etymology
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.
