MR imaging in deep pelvic endometriosis: a pictorial essay.

Abstract: In this pictorial review, MR imaging findings of deep infiltrating endometriosis (DIE) are illustrated together with surgical correlation. DIE can appear as irregular nodules or plaques with similar signal intensity to muscle on both T1-weighted and T2-weighted images. Hemorrhage foci and strands or stellate margins are also often noted.

Deep pelvic endometriosis can affect fibromuscular pelvic structures, such as the rectovaginal septum and uterosacral ligaments (69.2%), vagina (14.5%), alimentary tract (9.9%), urinary tract (6.4%), and other extraperitoneal pelvic sites. 2 Of the 3 forms of pelvic endometriosis, deep pelvic endometriosis is thought to contribute the most to pelvic pain and infertility.

Magnetic resonance imaging has long been the method of choice for the assessment of pelvic disorders (3-6). Although laparoscopy is the gold-standard test to establish a diagnosis of deep endometriosis, transvaginal ultrasound (TVUS) can contribute to its detection, because it is an accessible, noninvasive examination that allows preoperative planning in cases requiring surgical treatment ( 7 ).

Extragenital endometriosis at MRI shows as solid masses or soft-tissue thickening, with low-to-intermediate signal in both T 2 and T 1 weighted images (like most fibrotic lesions); the margins are usually irregular or stellate. Small superficial implants can be found on the serosa of any abdominal organ and they lack the infiltrative behaviour typical of deep endometriosis foci.

Deep pelvic endometriosis, also called deep infiltrating endometriosis, defined as the presence of invasive endometriotic lesions extending more than 5 mm from the peritoneal surface into adjacent structures and is associated with fibrosis and muscular hyperplasia.

The paired uterosacral ligaments are one of the supporting structures of the uterus. Uterosacral ligaments are not infrequently affected in cases of deep infiltrating endometriosis. Gross anatomy The paired uterosacral ligaments are extraperito.

The purpose of this article is to familiarize the radiologist with the wide spectrum of pelvic endometriosis and to review the distinctive imaging findings. Infrequent manifestations of endometriosis, including malignant degeneration, scar endometriosis, association with ascites, and invasive endometriosis, are described. CONCLUSION.

Pelvic MR imaging at 3.0 T could be the solution to the previously mentioned limitations of MR and provides the best results for the diagnosis and the preoperative staging of deep endometriosis. In the study by Hottat et al., MR at 3.0 T made it possible to complete the exploration of pelvis with very high spatial resolution allowing especially the detection of thin structures such as.

Review of MR imaging in last 12 months of cases presented locally at our Endometriosis multidisciplinary meeting at a district general hospital. We present a pictorial essay to show extent of pelvic disease as well as urinary tract, GI tract and pleural involvement.

Deep pelvic endometriosis is defined as subperitoneal infiltration of endometrial implants in the uterosacral ligaments, rectum, rectovaginal septum, vagina, or bladder. It is responsible for severe pelvic pain. Accurate preoperative assessment of disease extension is required for planning complete surgical excision, but such assessment is difficult with physical examination.
