The female anatomic equivalent of the male processus vaginalis is the canal of Nuck. The canal is formed from a small peritoneal protuberance from the round ligament that extends through the inguinal ring, into the inguinal canal, and terminates in the labia majora. Obliteration of the canal occurs in a superior to inferior direction and usually completes within the first year of life. Non-closure results in a persistent canal of Nuck. Very rarely herniation of abdominal and pelvic contents into the canal of Nuck can occur, much less commonly in females than in the male equivalent. Hernias can present at any age but are most common in children. Recognition of this entity is especially important in cases of ovarian herniation due to the risk of incarceration.
We will provide a review normal anatomy, potential canal contents, the imaging appearance on ultrasound, CT, as well as MRI, and discuss differential diagnosis using cases of canal of Nuck hernia in 4 patients aged 22 days though 17 years. Read More

This educational exhibit will present the importance and utility of utilizing ultrasound and various sonographic-imaging techniques to investigate and clarify the different types of pediatric hydroceles. It will convey the necessity for specifying the type of hydrocele in order to implement the best management protocols. Read More

The canal of Nuck, described by Anton Nuck in 1691, is an evagination of peritoneum into the labia majora and represents a patent processus vaginalis in females. While it usually undergoes obliteration soon after birth, it may be complicated by the accumulation of fluid (female hydrocele), or herniation of the bowel, the adnexa or the uterus into this potential space.We discuss the embryology of the Canal of Nuck and the various complications that may arise in infants and young girls with a patent canal.

The canal of Nuck is an evagination of the parietal peritoneum in females which extends along the round ligament of the uterus through the inguinal canal to the labium majorum and is usually obliterated by 8 months of gestation. Incomplete obliteration of the canal can predispose to an indirect inguinal hernia or a hydrocele in female children. In addition, other pathologies such as cysts or endometriosis can rarely occur. We present two cases of canal of Nuck pathology including a 5 year old female with a palpable left labial mass shown on ultrasound to be a canal of Nuck cyst and a 3 week old female with a left labial mass which on ultrasound showed a canal of Nuck hernia containing the left ovary. We will review the presenting history and characteristic imaging features in each case. Read More
