Patient Data

Age: 35 years
Gender: Female

Convoluted cystic structure localized in the right inguinal canal, extended up to the ipsilateral labia majora, with the opening at the proximal portion of the canal of Nuck.

Case Discussion

During fetal life from the abdominal cavity, two diverticula originate in the genital region. The peritoneum-vaginal duct In the male, this diverticulum, called a peritoneo-vaginal duct, helps to form one of the testicles in the scrotum at its lower end. In the female, however, the diverticula, called the Nuck channel, ends at the level of labia majora. 

At birth and in the following months, these diverticula undergo a physiological closure. However, it may happen that the closure does not occur or does not occur fully, allowing the abdominal viscera to penetrate the diverticula, resulting in an inguinal hernia with the classic swelling.

In females, the diverticulum can result in an inguinal hernia, or in a fluid collection, called canal of Nuck cysts.
