[Interstitial inguinal hernia in the infant]

Two infants aged four and eight weeks required an operation for an interstitial inguinal hernia. The clinical picture of this rare form of hernia is characteristic. There is a swelling in the abdominal wall between the internal inguinal ring and the anterior superior iliac spine. In addition there is almost always an ectopic testis on the affected side. Incidence, clinical picture and anatomy of the interstitial hernia are discussed.
