Cyst of the Canal of Nuck Mimicking Inguinal Hernia: A Case Report

Acu L and Acu B

A 22-year-old female patient was referred to our department by general surgeon for a suspected left-sided inguinal hernia. She had a painful tender mass in her left groin. On physical examination, there was a palpable mass in the region of her left inguinal canal. US and pelvic CT examination were performed. Sonographic examination, revealed a well-defined cystic mass with internal septae and thin wall, located in the left inguinal canal extending along the course of the round ligament. On CT images, there was a thin-walled cystic mass in the left inguinal canal and intraabdominal extension of the canal of Nuck. Diagnosis of cyst of the canal of Nuck was confirmed by surgery and subsequent histopathologic evaluation. Hydrocele of the canal of Nuck is a rarely encountered entity. It should be on the differential diagnosis list of groin swellings in female patients. Radiologists must be aware of the imaging findings of hydrocele of the canal of Nuck to diagnose this entity before surgery.
