Three dimensional sonovaginography to assess posterior fornix and rectovaginal endometriosis - a new approach.

Deep infiltrating endometriosis (DIE) is characterized by foci of ectopic endometrial tissue, fibrosis and muscular hyperplasia that penetrate more than 5 mm into affected pelvic organs. Endometriosis of the rectovaginal septum (RVS-DIE) is the most severe form of DIE and has been described as endometriotic lesions that infiltrate both rectum and posterior vaginal fornix with possible extension to the rectovaginal septum. There are doubts regarding the definition and nomenclature involving this topography. This article is protected by copyright. All rights reserved.
