Paratubal or Paraovarian Cysts

Synonyms/Description

Adnexal cyst, mesothelial or paramesonephric cyst

Etiology

Paratubal and paraovarian cysts arise from the broad ligament. They constitute 10% of adnexal masses. They are usually benign but may rarely (reportedly 2%) contain malignant or borderline elements.

Etiologies for paratubal cysts include mesosalpingeal cysts, hydatid cysts of Morgagni, and paratubal subserosal cysts arising from Müllerian duct remnants, as opposed to paraovarian cysts, which arise from mesonephric tubules (Wolffian duct) and are mesothelial in origin.
