Inguinal herniae are common in preterm infants.  They result from failure of closure of the processus vaginalis - a covering or peritoneum that encloses the testicles during their descent into the scrotum.  Bowel is able to enter the inguinal canal.  They are most common in males (90%), and up to 15% of infants will have bilateral herniae (in preterm infants, it is common to repair both sides even if a hernia is present on one side).  A palpable hernia in a female could represent an ovary.

It is important to differentiate between a hernia and a hydrocoele.  In a hernia, bowel enters the inguinal canal.  There is a mass at the inguinal ring which can usually be reduced. Hydrocoeles are collections of fluid within the processus vaginalis and scrotum - one can palpate above them, they transilluminate, and are irreducible.
