Laparoscopic surgery for a hydrocele of the canal of Nuck with an ovarian tumor: an extremely rare clinical finding

This clinical image presents an unusual report of simultaneous laparoscopic resection of a hydrocele of the canal of Nuck and an ovarian tumor. Laparoscopic treatment with a proper approach is a useful technique in some cases.

EP.FRI.48 Right iliac fossa pain in females: more than appendixes and ovarian cysts; Haemorrhagic Cyst in the Canal of Nuck: A Case Report

Case report A 43-year-old woman presented with acute onset migratory right iliac fossa pain, on a background of intermittently painful right groin swelling. CT demonstrated differential diagnosis of appendicitis besides an ovarian cyst. Diagnostic laparoscopy was undertaken with a view to diagnosis and treat possible appendicitis, ovarian cyst and inguinal hernia. To our surprise, a haemorrhagic nuchal cyst was seen intraoperatively, and duly aspirated. Post-operatively she recovered well and was discharged the same day. Introduction The Canal of Nuck is a small evagination of parietal peritoneum which accompanies the round ligament through the inguinal canal, in females. It is obliterated in the first year of life. When this remains patent, it can fill with fluid and result in the formation of cysts (akin to hydroceles in patent processus vaginalis). In current literature there are only sixteen case reports of Nuck hydroceles in adults, with only one haemorrhagic cyst reported. These are typically diagnosed in children, but occasionally present in women (aged 35.18 ± 3.27) with groin swelling and are frequently misdiagnosed as hernias. It is only when these woman are taken to theatre, that the correct diagnosis is discovered. Conclusion This case highlights the importance of considering Canal of Nuck cysts when women present with groin swellings, to ensure quick diagnosis and appropriate management is delivered under the correct speciality.

A rare case of left Nuck’s canal cystic endometriosis: Computed Tomography findings

Introduction: Endometriosis is a common and chronic gynaecological condition but the implant in the canal of Nuck constitutes a very unusual state with an estimated prevalence of 0.3%–0.6% of all endometriosis cases. The canal of Nuck is an abnormal patent pouch of parietal peritoneum extending anteriorly from the round ligament of the uterus into the labia majora, thus represents a communication between the peritoneal cavity and the female inguinal canal. This condition may permit the seeding of endometriotic tissue in the inguinal soft tissues, becoming a possible cause of inguinal swelling or pain. Case description: A 43-years-old woman presented with painful swelling in her left groin. Ultrasound and a subsequent pelvic computed tomography showed a cystic lesion as for a Nuck’s canal encysted hydrocele. The patient underwent an anterior open surgery and the histologic examination revealed an endometrium-like tissue in the cystic wall. Conclusion: In women presenting with painful swelling of the groin, despite its rarity, endometriosis of the Nuck’s canal must be differentiated from other more common pathologies like hernias, varicoceles, neoplasms, and lymphadenopathies. Imaging can aid in differential diagnosis, but the final diagnosis is entrusted to histology, which enable to exclude an underlying malignancy.
