A Rare Case Report of Out of the Ordinary Canal of Nuck Hernia Encompassing Pelvic Structures, Showing up as a Labial Mass

Abstract

Aim and objective: We report a rare case of the canal of Nuck hernia containing part of the uterus and both ovaries as its contents. The aim is to build up the awareness of this condition by reviewing the ultrasound and MRI imaging findings and identification of prolapsed ovary with correct knowledge of the entity and focused analysis. Background: The patent canal of Nuck is one of the rare developmental entities in females. Hernia of the canal of Nuck is an extension of the peritoneal fold through the inguinal canal up to the labia majora. Defective obliteration of this peritoneal fold leads to herniation of abdominal content into the inguinal canal. Case description: An exceptionally rare case of a 5-month-old female child who presented to us with a palpable, non-tender, left labial mass. Ultrasound and MRI were performed showing the contents of herniating sac as uterine fundus and bilateral ovaries along with minimal free fluid. The infant was managed conservatively and kept under follow-up. Conclusion: Incidence of both ovary and uterus as contents of hernia is very rare. Furthermore, early and correct identification of the herniated ovary prevents an uncalled-for surgery. Clinical significance: It is very important to be familiar with this entity, especially in cases of ovarian hernia due to the risk of associated complications like incarceration and torsion.
