What is a Hydrocoele of the Spermatic Cord?

Discussion Hydrocoeles are common anatomic variations caused by the incomplete obliteration of the processus vaginalis. The processus vaginalis is a peritoneal remnant that follows the testis and spermatic cord into the scrotum as the testis descends into the scrotum during development. As the processus vaginalis traverses from the testis back to the peritoneum, a hydrocoele can occur at any point along its length. The obliteration of the processus vaginalis occurs with the closure at the internal inguinal ring, followed by closure just above the testes with atresia of the area in between. The closure of the area around the testes itself is often not complete by the time of birth and hydrocoeles are commonly seen in the scrotum; most resolve by 1 year of age. The hydrocoeles may be uni- or bilateral. Learning Point Hydrocoele of the spermatic cord (HSC) is a uncommon variation of hydrocoele. There can be a chronic or acute onset of swelling in the upper groin or inguinal area above the testis and epididymis. HSC is divided into 2 or 3 types depending on the author. An encysted HSC occurs when there is obliteration of the processus vaginalis at both ends with solitary cyst formation. This does not change in size. A funicular HSC occurs when there is obliteration of the processus vaginalis distally leaving open the proximal processus vaginalis to communicate with the peritoneum. This may change in size because of differing amounts of peritoneal fluid in the cyst. A mixed HSC ...
