A tubular cystic lesion is seen in the left inguinal canal extending towards labia. On transverse section, the lesion is seen anteromedial to the femoral vessels.


MRI pelvis

A lobulated tubular cystic lesion is seen in the left groin. It is entering the left inguinal canal from an intrapelvic location and exiting at the level of the external inguinal ring, extending towards the labia. It is hyperintense on T2WI, T2 fat sat and hypointense on T1WI.

Incidentally noted arcuate uterus.

Case Discussion

The canal of Nuck is a pouch of parietal peritoneum extending to the labium majus and is a structural analog of the processus vaginalis in males. Although it usually disappears in the first week of life, it may on rare occasions remain patent and give rise to a hydrocele of the canal of Nuck or even an indirect inguinal hernia
