A cautionary approach to adult female groin swelling: hydrocoele of the canal of Nuck with a review of the literature.

Hydrocoele of the canal of Nuck in an adult female is a rare entity and analogous to hydrocoele in males. Its usual presentation is in children, and its occurrence in adults is very uncommon, more so of the hour-glass variety. We report a case of a 38-year-old woman presenting with a right inguinal swelling of 3-month duration. On physical examination, the swelling was non-tender, cystic and irreducible. There was no cough impulse. Ultrasonography and contrast-enhanced CT revealed a cystic swelling with clear contents in the right inguinal region. Surgery was performed with excision of the cyst. The histopathology report suggested flat mesothelium cells, confirming the diagnosis. 2016 BMJ Publishing Group Ltd.
