"Femoral hernias (alternative plural: herniae) are a type of groin herniation and comprise a protrusion of a peritoneal sac through the femoral ring into the femoral canal, posterior and inferior to the inguinal ligament. The sac may contain preperitoneal fat, omentum, small bowel, or other structures."
"There may be an increased right-sided predilection 2,3. There is an increased prevalence in females 6."
"Occasionally, a femoral hernia may develop differently or be located somewhere besides medially to the femoral vessels. Possibilities include a hernia developing through the lacunar ligament (Laugier hernia), or through the pectineal fascia (Cloquet hernia) 7. Femoral hernias in an atypical relation to the femoral vessels include those lateral (Hesselbach hernia), prevascular (Velpeau hernia) or retrovascular (Serafini hernia) 7."
