Amyand's hernia is a rare condition whereby the appendix lies within the sac of an inguinal hernia; rarer still, the appendix can become inflamed (acute appendicitis) and is frequently misdiagnosed as a strangulated inguinal hernia. We report a case of Amyand's hernia complicated with acute appendicitis. In this case an accurate preoperative diagnosis was provided by a preoperative Computerised Tomography (CT) scan, permitting planning of treatment by a laparoscopic approach.
