Inguinal Hernia vs. Cryptorchidism
Left picture: The visible increase of volume of the right groin is due to an inguinal hernia. The additional findings of a somewhat larger testicle and of a prominent navel are possibly due to a testicular hydrocele and a skin navel, or a small umbilical hernia. Right picture: The palpable increase of volume of the right groin is not due to an inguinal hernia or a lymphadenopathy. In the picture at the bottom, the right testis becomes visible and palpable during an examination in a sitting position, and corresponds to the longitudinal-oval and solid mass palpated close to the external inguinal ring. But on releasing, the testis returns to its position in the groin. The diagnosis is a sliding testis (prefascial ectopy of cryptorchidism).
Left picture: In this infant an increase of volume of the right groin attracts attention in comparison to the left side. The right testis is higher in its scrotal compartment than the left one, and somewhat larger. In addition, the navel is prominent. Right picture: In this toddler an increase of volume of the left inguinal region seems to be more likely. On palpation, no corresponding finding is present. On the other hand, in the right groin a longitudinal-oval and solid mass can be palpated close to the external inguinal ring. Left picture: The increase of volume of the right groin feels smooth and can be removed by finger pressure.
