Female hydrocele of the canal of Nuck: a case report.

The processus vaginalis is an evagination of parietal peritoneum which accompanies the round ligament through the inguinal ring into the inguinal canal. The portion of processus vaginalis within the inguinal canal in women is called 'the canal of Nuck'. When the processus vaginalis fails to close, it can result in a hernia or hydrocele, both in women and men. Female hydrocele of the canal of Nuck is uncommon. A literature search revealed that little has been published on this condition. We present a case of a hydrocele of the canal of Nuck in a 5-month-old female infant.
