The value of pelvic MRI in the diagnosis of posterior cul-de-sac obliteration in cases of deep pelvic endometriosis.

Objective: The objective of our study was to define relevant MRI signs allowing preoperative diagnosis of posterior cul-de-sac obliteration in patients with deep pelvic endometriosis.

Three radiologists performed the MRI review blinded and recorded the following signs: sign 1, retroflexed uterus; sign 2, retrouterine mass; sign 3, displacement of intraperitoneal fluid; sign 4, elevation of the fornix; and sign 5, adherence of bowel loops.
