Ultrasound has been successfully utilized, mostly outside North America, to preoperatively stage deep endometriosis, but in these international settings, imaging is typically performed solely by expert radiologists and gynecologists. We outline a method for detailed sonographic survey of the lower abdomen and pelvis to ensure optimum detection and communication of disease extent that is geared to radiologists practicing ultrasound in the United States, with the use of diagnostic medical sonographers.\nSimilar content being viewed by others\nReferences\nEskenazi B, Warner ML (1997) Epidemiology of endometriosis.

The transducer is seated in the anterior fornix, just in front of the anterior cervical lip, adjacent to the urinary bladder. Note the sharp, smooth interface between the posterior wall of the cervix and the bowel and retrocervical adipose deep to the cervix and uterine body. Free motion is evident during ballottement (AVI 9067 KB).\n261_2016_886_MOESM2_ESM.avi (download AVI )\nVideo 2: Uterine sliding sign, abnormal appearance. Note the irregular, hypoechoic interface between the cervix and retrocervical/rectal endometriotic implant. Findings are consistent with posterior cul-de-sac obliteration “frozen pelvis” (AVI 9026 KB).\nRights and permissions\nAbout this article\nCite this article\nYoung, S.W., Saphier, N.B., Dahiya, N. et al.
