US findings of uterine and ovarian herniation through the Nuck canal: a case report

| Summary: | The processus vaginalis peritonei, a tubular fold of the peritoneum that invaginates into the inguinal canal, called the canal of Nuck, is normally obliterated in women. However, if the processus vaginalis remains open, the parietal peritoneum extends through the inguinal canal to the labia majora, resulting in a Nuck canal hernia (NCH). High-frequency ultrasound (US) is the initial method preferred for the diagnosis of NCH. The aim of this case report is to describe the US findings in a 2-month-old girl with pelvic swelling diagnosed as an NCH involving the uterus and ovary. A pelvic US of the left labia majora showed a hernia sac with fatty ovarian and partial uterine contents. The ovary measured 1.6 x 0.9 x 0.8 cm without adequate blood flow on color and power Doppler. Blood flow was visible in the pedicle. Fluid, edema, and increased adjacent soft tissue echogenicity were also noted in the hernia sac, findings consistent with NCH. Subsequent surgical reduction was performed to avoid complications due to the loss of blood supply to the ovary. This case report is the first from Mexico to highlight the findings of NCH of the uterus and ovary. It is presented for educational purposes.
