Femoral hernias can be difficult to diagnose and are at high risk of strangulation. This report is of a rare case of an irreducible femoral hernia containing caecum and appendix presenting as an emergency. To the authors’ knowledge, there have only been three cases reported, the first described by Duari. This case was incorrectly diagnosed preoperatively as an inguinal hernia, so the CT diagnosis of femoral hernias is reviewed, in particular demonstrating the radiological use of the femoral vein compression sign.
