Introduction: Hydroceles of the canal of Nuck are rare, and have not been described in relation to pregnancy.
Case presentation: A 34-year-old Caucasian female patient had bilateral groin swelling debuted during her pregnancy. A preoperative magnetic resonance imaging scan found bilateral hydroceles of the canal of Nuck. Operative findings and histological examinations revealed a left-sided inguinal hernia and a right-sided hydrocele. The patient was discharged well and without signs of postoperative complications or hernia recurrence.
Discussion: In this case, a hydrocele and a hernia sac were morphologically identical in terms of preoperative appearance and development. Given the morphological correlation, it was surprising to find different operative findings confirmed by the histopathological examination.
Conclusion: This is the first ever report of the synchronic development of two morphologically identical cystic processes, with one being a hydrocele and the other a hernia sac. In addition, the hydrocele developed during pregnancy, making this case even more unique.
