We report here the case of a 25-year-old woman admitted with a tender and painful right inguinal swelling. The CT scan showed a fluid image in the right iliac fossa (RIF), in contact with the external iliac vessels, the sigmoid colon and some small intestines, extending downwards from a dehiscence of the right inguinal canal. The diagnosis of Nuck's duct cyst (female hydrocele) was accepted and surgically confirmed. The cyst of the canal of Nuck is due to incomplete closure of the canal, resulting in a vestigial fibrous structure of the peritoneovaginal canal which connects the peritoneal cavity to the greater lip. This cyst generally closes at birth or during the first month of life, resulting in the formation of a cystic lesion lined with mesothelium, mainly flattened and sometimes hyperplastic, located in the anterosuperior part of the labia majora and/or inguinal canal. Nuck's duct cysts are treated surgically in the same way as hernias.
