Incarcerated Femoral Hernia

Incarcerated femoral hernia. The 92 year old woman presented with acute abdominal pain and distension. Her PFA (a) shows multiple dilated small bowel loops in the centre and left side of her abdomen. CT (b) showed a hernia in the left groin, containing small bowel (arrow). This is displacing and compressing the femoral vein (arrowhead), a reliable indicator that it is a femoral rather than an inguinal hernia. Coronal CT image (c) shows the constriction of the small bowel in the neck of the hernia (arrowheads).
