Differential diagnosis table of Epiploic Appendagitis in a Femoral Hernia.

Differential Diagnoses	Computed tomography (CT) findings
Epiploic appendagitis within a femoral hernia	High density ‘dot’ in a fat density centre, which is surrounded by a high attenuation rim and inflammatory changes. These changes are within a hernia with a ‘funnel shaped’ neck, protruding through the femoral ring, and sometimes compressing the common femoral vein.
Epiploic appendagitis within an inguinal hernia	High density ‘dot’ in a fat density centre, which is surrounded by a high attenuation rim and inflammatory changes. These changes are within a ‘lateral crescent’ shape and extend anteromedially and inferiorly to the inferior epigastric vessels.
Appendicitis within a femoral hernia	Dilated, inflamed appendix with a thick and enhancing periphery as well as thickening of the caecal apex. These changes are within a right sided hernia with a ‘funnel shaped’ neck, protruding through the femoral ring, and sometimes compressing the common right femoral vein.
Colonic diverticulitis within a femoral hernia.	Focal areas of pericolic inflammatory stranding adjacent to bowel diverticula. These changes are within a hernia with a ‘funnel shaped’ neck, protruding through the femoral ring, and sometimes compressing the common femoral vein.
