Answer

Prevascular femoral hernia is rare and manifests as a bulge that may be mistaken for a femoral aneurysm. External femoral hernias pass beneath the inguinal ligament to lie lateral to the femoral vessels and deep to the iliopubic tract. A hernia of Laugier traverses a defect in the lacunar ligament. A hernia of Cloquet results from an abnormal insertion of the pectineus, which allows perforation of the aponeurosis as the hernia sac courses over the femoral canal. The retrovascular hernia sac descends in the posterior sheath of the femoral vein.
