Parovarian cyst presenting as a groin hernia. A case report.

An inguinal hernia containing a parovarian cyst is extremely rare. This phenomenon occurred in a 77-year-old woman who presented with a right groin hernia. The hernia contained a cystic mass that arose between the leaves of the broad ligament and passed with the round ligament through the deep inguinal ring. Through a midline incision the hernial content was mobilized, reduced through the inguinal ring and removed from the abdomen with both ovaries, tubes and uterus. The mass was found to be a parovarian cyst of the mesothelial type.
