Hydrocele of the canal of Nuck presenting as a sausage-shaped mass.

A 23-year-old woman presented with a painless vulval swelling. On physical examination, a soft fluctuant sausage-shaped mass was found, measuring approximately 4 cm, extending from the right inguinal region to the labia majora. Ultrasound revealed a well-defined hypoechoic elongated mass, septated, extending from the superficial inguinal canal to labia majora. Sonographic findings were consistent with the diagnosis of a hydrocele of the canal of Nuck. Surgical exploration revealed an elongated cystic lesion with a total length of 13 cm, mucous component and internal septations. Histopathological examination of the surgical specimen confirmed the suspected diagnosis. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017. All rights reserved.
