NON-COMMUNICATING HYDROCOELE OF THE CANAL OF NUCK: A RARE FINDING IN A RURAL-DWELLING NIGERIAN WOMAN.

Abstract

Background: The surgical condition termed hydrocoele of the canal of Nuck is one of the rarest clinical entities in the female group. It occurs due to the failure of obliteration of the derivative of the peritoneum, the processus vaginalis. It usually presents with painless inguinal swellings and is sometimes associated with features of intestinal obstruction if there is hernia coexisting with it that has become obstructed. Abdominopelvic ultrasonography and magnetic resonance imaging provide the basis for diagnosis, where these imaging modalities are available. However, a definite diagnosis may only be made during surgery. Definitive treatment includes groin exploration and excision of the cyst with high ligation of the neck of the sac up to the peritoneal pouch, along with repair of the inguinal hernia, if present.

Case presentation: We present a rare case of a 34-year-old woman who presented with clinical features of a left inguinolabial swelling post-surgery, and diagnosed as left recurrent irreducible inguinal hernia. Intraoperatively, a cystic swelling with serous collection was observed. She had hydrocoelectomy and repair of the left groin surgical wound.

Conclusion: Hydrocoele of the canal of Nuck may be misdiagnosed as inguinal hernia because of its rarity, lack of adequate knowledge regarding the entity and paucity of literature on the subject matter. This report is to furthermore increase our level of awareness of this condition especially after a previous groin surgery.
