Using sterile technique and local anaesthesia, a 22G Chiba needle was inserted into the peritoneal cavity and 50 mL of non-ionic contrast was injected. The patient was asked to walk for 10 minutes before taking films.
Plain film of the pelvis shows contrast outlining loops of bowel. A left-sided hernia is seen filled with contrast containing a narrow neck that parallels the superior pubic ramus.
Surgery confirmed presence of this femoral hernia.
Femoral hernias are less than 10% as frequent as inguinal hernias. They are more common in females and on the right side. They may be difficult to distinguish from indirect inguinal hernias.
Femoral hernias have a narrow neck while passing through the femoral canal and are prone to incarceration. On herniography the direct hernia is described as pear-shaped with a narrow neck. The upper posterior border of the neck parallels the superior pubic ramus.
