Axial contrast-enhanced CT images (a-d) demonstrate the appendix (solid arrows) entering into the right femoral hernia sac in keeping with a de Grangeot hernia. Within the hernia sac there is a fluid collection (dashed arrows) concerning for abscess or mucocele. Findings are confirmed on the sagittal reformatted image (e).

A contrast-enhanced CT of the abdomen and pelvis was obtained for further evaluation which demonstrated a fat- and fluid-containing right femoral hernia (Figures 1 and 2).
Coronal contrast-enhanced CT images demonstrate the appendix (solid arrows) entering into the right femoral hernia sac with surrounding periappendiceal fat stranding (dashed arrow) in keeping with chronic appendicitis.
