Abstract
We present a new systematic, comprehensive, checklist-based sonographic assessment of endometriosis in the female true pelvis. Emphasis is placed on practical skills teaching. The newly introduced White Sliding Line (WSL) is the core structure. The WSL separates five compartments (anterior, central, posterior, and lateral right and left) containing dedicated endometriosis signs of mobility and morphology to be checked. This approach relies on the 2016 IDEA Consensus and further developments. It directly connects to the 2021 #ENZIAN Classification Standard. In practice, evaluation follows the proposed checklist in all compartments, judging first sliding mobility between organs and structures in a highly dynamic investigation. A rigorous search for deep endometriosis (DE) is then performed. We treat adhesions due to their great clinical importance and possible, reliable diagnosis by TVS as the fifth endometriosis unit, next to endometrioma, DE, adenomyosis, and superficial endometriosis. Including superficial (peritoneal) endometriosis is a future goal.

Ultrasonographic characterization of parametrial endometriosis: a prospective study. Fertil Steril 2024; 122:150-161. [PMID: 38382700 DOI: 10.1016/j.fertnstert.2024.02.031] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2023] [Revised: 02/13/2024] [Accepted: 02/14/2024] [Indexed: 02/23/2024]
Abstract
OBJECTIVE To study the ultrasonographic diagnostic accuracy and characteristics of parametrial endometriosis comprehensively. DESIGN This prospective study enrolled patients with suspected deep endometriosis (DE) scheduled for laparoscopic surgical treatment. Preoperative ultrasonographic examinations were performed following the International Deep Endometriosis Analysis criteria. This study aimed to evaluate the presence of parametrial endometriosis and its ultrasonographic characteristics, using surgical diagnosis as the reference standard. Additionally, indirect signs of DE and concomitant DE nodules associated with parametrial involvement were identified, assessing their predictive significance in the anterior, lateral, and posterior parametrial areas. SETTING Referral institution for endometriosis. PATIENTS Patients with suspected DE scheduled for surgical treatment. INTERVENTIONS Standardized preoperative ultrasonographic examination. MAIN OUTCOME MEASURES The diagnostic accuracy of transvaginal ultrasound in identifying parametrial endometriosis, including sensitivity and specificity, and the ultrasonographic characteristics of parametrial nodules, prevalence in distinct parametrial areas, and associations with indirect DE signs and concomitant DE nodules. RESULTS Surgical confirmation of parametrial nodules was observed in 105 of 545 patients (left, 18.5; right, 17.0%). Transvaginal ultrasound demonstrated a sensitivity of 77.1% (95% confidence interval, 68.0%-84.8%) and specificity of 99.1% (95% confidence interval, 67.7%-99.8%). Parametrial nodules typically exhibited characteristics such as a mild hypoechoic appearance (83.6%), starry morphology (74.7%), irregular margins (70.2%), and low vascularization. The posterior parametrial region was the most common location (52.2%), followed by the lateral (41.0%) and anterior (6.8%) parametrial regions. Concomitant DE nodules in the rectum (63.5%) and infiltrating the rectovaginal septum (56.5%) were significantly more prevalent in patients with parametrial involvement. Indirect DE signs, such as the ovaries fixed to the uterine wall (71.8%) and the absence of a posterior sliding sign (51.8%), were also more common in women with parametrial nodules. Hydronephrosis, although relatively uncommon in patients with parametrial involvement (8.2%), was largely detected in lateral parametrial nodules (70.0%). CONCLUSIONS This study represents a systematic ultrasonographic characterization of parametrial endometriosis. Specifically, it comprehensively assesses the diagnostic accuracy of transvaginal ultrasound in identifying parametrial involvement within a sizable cohort of patients with preoperative suspicion of DE. CLINICAL TRIAL REGISTRATION NUMBER NCT06017531.

Society of Radiologists in Ultrasound Consensus on Routine Pelvic US for Endometriosis. Radiology 2024; 311:e232191. [PMID: 38591980 PMCID: PMC11070694 DOI: 10.1148/radiol.232191] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2023] [Revised: 11/21/2023] [Accepted: 12/22/2023] [Indexed: 04/10/2024]
Abstract
Endometriosis is a prevalent and potentially debilitating condition that mostly affects individuals of reproductive age, and often has a substantial diagnostic delay. US is usually the first-line imaging modality used when patients report chronic pelvic pain or have issues of infertility, both common symptoms of endometriosis. Other than the visualization of an endometrioma, sonologists frequently do not appreciate endometriosis on routine transvaginal US images. Given a substantial body of literature describing techniques to depict endometriosis at US, the Society of Radiologists in Ultrasound convened a multidisciplinary panel of experts to make recommendations aimed at improving the screening process for endometriosis. The panel was composed of experts in the imaging and management of endometriosis, including radiologists, sonographers, gynecologists, reproductive endocrinologists, and minimally invasive gynecologic surgeons. A comprehensive literature review combined with a modified Delphi technique achieved a consensus. This statement defines the targeted screening population, describes techniques for augmenting pelvic US, establishes direct and indirect observations for endometriosis at US, creates an observational grading and reporting system, and makes recommendations for additional imaging and patient management. The panel recommends transvaginal US of the posterior compartment, observation of the relative positioning of the uterus and ovaries, and the uterine sliding sign maneuver to improve the detection of endometriosis. These additional techniques can be performed in 5 minutes or less and could ultimately decrease the delay of an endometriosis diagnosis in at-risk patients.

Abstract
The Kissing ovaries sign is a radiological sign seen in women with deep pelvic endometriosis. It refers to abutment of the ovaries within the cul-de-sac. The term kissing ovaries was first described by Ghezzi et al. (2005) and has been since used widely. When seen on imaging it indicates moderate to severe endometriosis with the ovaries tethered within abnormal pelvic soft tissue, which may warrant surgical management.

[PMID: 36591808 DOI: 10.1016/j.jmig.2022.10.008] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2022] [Revised: 10/23/2022] [Accepted: 10/24/2022] [Indexed: 11/22/2022]
Abstract
STUDY OBJECTIVE To evaluate ultrasonographic findings as a first-line imaging tool to indirectly predict the presence of parametrial endometriosis (PE) in women with suspected deep endometriosis (DE) undergoing surgery. DESIGN Retrospective analysis of a prospectively collected database (ULTRA-PARAMETRENDO I study; NCT05239871). SETTING Referral center for DE. PATIENTS Consecutive patients undergoing laparoscopic surgery for DE. INTERVENTIONS Preoperative transvaginal ultrasonography was done according to the International Deep Endometriosis Analysis consensus statement. A stepwise forward regression analysis was performed considering the simultaneous presence of DE nodules and the following ultrasonographic indirect signs of DE: diffuse adenomyosis, endometriomas, ovary fixed to the lateral pelvic wall or the uterine wall, absence of anterior/posterior sliding sign, and hydronephrosis. The gold standard for the presence of PE was surgery with histologic confirmation. MEASUREMENTS AND MAIN RESULTS Of 1079 patients, 212 had a surgical diagnosis of PE (left: 18.5%; right: 17.0%; bilateral: 15.9%). The obtained prediction model (χ2 = 222.530; p <.001) for PE included, as independent indirect DE signs presence of hydronephrosis (odds ratio [OR] = 14.5; p = .002), complete absence of posterior sliding sign (OR = 3.3; p <.001), presence of multiple endometriomas per ovary (OR = 3.0; p = .001), and ovary fixation to the uterine wall (OR = 2.4; p <.001); as independent concomitant DE nodules, presence of uterosacral nodules with the largest diameter >10 mm (OR = 3.2; p <.001), presence of rectal endometriosis with the largest diameter >25 mm (OR = 2.3; p = .004), and rectovaginal septum infiltration (OR = 2.3; p = .003). The optimal diagnostic balance was obtained considering at least 2 concomitant DE nodules and at least 1 indirect DE sign (area under the curve 0.75; 95% confidence interval, 0.72-0.79). CONCLUSION Specific indirect ultrasonographic findings should raise suspicion of PE in women undergoing preoperative assessment for DE. The suspicion of parametrial invasion may be critical to address patients to expert leading centers, where proper diagnosis and surgical treatment for PE can be performed.

Prevalence of endometrioma and deep infiltrating endometriosis at transvaginal ultrasound examination of subfertile women undergoing assisted reproductive treatment. Fertil Steril 2022; 118:915-923. [PMID: 36175206 DOI: 10.1016/j.fertnstert.2022.07.024] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/08/2022] [Revised: 07/26/2022] [Accepted: 07/28/2022] [Indexed: 01/13/2023]
Abstract
OBJECTIVE To estimate the prevalence of endometrioma and deep infiltrating endometriosis (DIE), assessed by systematic transvaginal ultrasound examination, in women with subfertility accepted for their first assisted reproductive treatment and to describe the prevalence of endometriotic lesions in different anatomical locations of the pelvis. DESIGN Cross-sectional study. SETTING Reproductive Medicine Center, Department of Obstetrics and Gynecology, University hospital. PATIENT(S) A total of 1,191 women with subfertility aged 25-39 years accepted for their first assisted reproductive treatment between December 2018 and May 2021. INTERVENTION(S) All women underwent a systematic transvaginal ultrasound examination. The endometriotic lesions visible on ultrasound examination were described according to the International Deep Endometriosis Analysis group consensus opinion for systematic approach to assess endometriotic lesions. MAIN OUTCOME MEASURE(S) Prevalence of endometrioma and DIE in women with subfertility and prevalence of endometriotic lesions in various anatomical locations of the pelvis. RESULT(S) Endometriosis prevalence was 21.8%, with endometriotic lesions found in 260 of the 1,191 women. Overall, 125 (10.5%) women had endometrioma and 205 (17.2%) women had DIE. Of these 260 women, 197 (75.8% of women with endometriosis) did not have any previous knowledge about having endometriosis. The most common location for endometriotic lesions was the uterosacral ligaments, with lesions found in 151 (12.7%) of all women. The second most common location was the ovaries containing endometrioma, found in 125 (10.5%) women. Most women had 1 (n = 121, 10.2%) or 2 (n = 82, 6.9%) endometriotic lesions. CONCLUSION(S) The prevalence of endometrioma and DIE in women with subfertility, diagnosed by systematic transvaginal ultrasound examination, was 21.8%. Of these, three-fourth of women had no knowledge about the presence of disease.

Abstract
PURPOSE To evaluate the relationship between gastrointestinal (GI) symptoms and transvaginal ultrasound (TVUS) findings suggestive of endometriosis. MATERIALS AND METHODS A prospective design. Women referred for a diagnostic ultrasound due to suspicion of endometriosis completed a Rome III and Pelvic Floor Distress Inventory (PFDI-20) questionnaire for clinical, GI symptoms, before undergoing TVUS. Endometriosis was diagnosed in the presence of endometriomas and/or deeply infiltrative endometriotic (DIE) lesions. Association between lesion sites and GI symptoms was evaluated by univariate and multivariate analysis. RESULTS The study included 241 women who presented with: dysmenorrhea (89.6 %), dyspareunia (76.3 %), chronic pelvic pain (77.2 %), dyschezia (66 %), hematochezia (15.4 %), subfertility (24.5 %). GI symptoms were present in 25.3-76.8 % and 5.4-55.6 % of Rome III and PFDI-20 questionnaire responses, respectively. TVUS findings were endometriomas (23.2 %), peritoneal adhesions (46.5 %), uterosacral ligament (26.7 %), retrocervical (11.2 %), rectosigmoid (11.2 %), intestinal (4.6 %), and bladder (0.8 %) involvement, and pouch of Douglas (POD) obliteration (15.4 %). There was a high prevalence of peritoneal adhesions, uterosacral ligament involvement, and rectosigmoid and intestinal nodules on TVUS in women with GI symptoms, up to Chi2 = 9.639 (p = 0.013) on univariate and Chi2 = 8.102 (p = 0.005) on multivariate analysis. CONCLUSION We observed an almost 10-fold increase in DIE lesions in women with GI symptoms. We suggest that the presence of GI symptoms should prompt a referral for endometriosis evaluation and performance of a dedicated TVUS before invasive gastrointestinal procedures.

Transvaginal Ultrasound vs. Magnetic Resonance Imaging (MRI) Value in Endometriosis Diagnosis. Diagnostics (Basel) 2022; 12:diagnostics12071767. [PMID: 35885670 PMCID: PMC9315729 DOI: 10.3390/diagnostics12071767] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/22/2022] [Revised: 06/24/2022] [Accepted: 07/18/2022] [Indexed: 11/16/2022] Open
Abstract
(1) Background: Endometriosis is a widespread gynecological condition that causes chronic pelvic discomfort, dysmenorrhea, infertility, and impaired quality of life in women of reproductive age. Clinical examination, transvaginal ultrasonography (TVS), and magnetic resonance imaging (MRI) are significant preoperative non-invasive diagnosis procedures for the accurate assessment of endometriosis. Although TVS is used as the primary line for diagnosis, MRI is commonly utilized to achieve a better anatomical overview of the entire pelvic organs. The aim of this systematic review article is to thoroughly summarize the research on various endometriosis diagnosis methods that are less invasive. (2) Methods: To find relevant studies, we examined electronic databases, such as MEDLINE/PubMed, Cochrane, and Google Scholar, choosing 70 papers as references. (3) Results: The findings indicate that various approaches can contribute to diagnosis in different ways, depending on the type of endometriosis. For patients suspected of having deep pelvic endometriosis, transvaginal sonography should be the first line of diagnosis. Endometriosis cysts are better diagnosed with TVS, whereas torus, uterosacral ligaments, intestine, and bladder endometriosis lesions are best diagnosed using MRI. When it comes to detecting intestine or rectal nodules, as well as rectovaginal septum nodules, MRI should be the imaging tool of choice. (4) Conclusions: When diagnosing DE (deep infiltrative endometriosis), the examiner’s experience is the most important criterion to consider. In the diagnosis of endometriosis, expert-guided TVS is more accurate than routine pelvic ultrasound, especially in the deep infiltrative form. For optimal treatment and surgical planning, accurate preoperative deep infiltrative endometriosis diagnosis is essential, especially because it requires a multidisciplinary approach.

Abstract
INTRODUCTION Prevalence of endometriosis is commonly reported based on surgery findings and varies widely depending on study population and indication for surgery. Symptoms such as dysmenorrhea, pelvic pain, dyspareunia, dysuria, and dyschezia can be associated with endometriosis and adenomyosis. Transvaginal ultrasound examination is proposed to be the first-line diagnostic method, nevertheless there are no published ultrasound-based studies reporting prevalence of endometriosis and adenomyosis in symptomatic women other than those scheduled for surgery. The aim of this study was to determine the prevalence of endometriosis and adenomyosis as assessed by transvaginal ultrasound in women with symptoms suggestive of endometriosis and adenomyosis. MATERIAL AND METHODS This is a retrospective cross-sectional study performed at a tertiary-care center including 373 symptomatic women who were systematically examined with transvaginal ultrasound by an experienced ultrasound examiner. Before ultrasound examination women filled in a questionnaire including self-assessment of the severity of their symptoms (dysmenorrhea, chronic pelvic pain, dyspareunia, dysuria, dyschezia) using a visual analog scale. Abnormal findings in the uterus, ovaries, bowel, urinary bladder, uterosacral ligaments, and rectovaginal septum were noted, and their size and location were described. Prevalence of endometriosis, adenomyosis, endometrioma, and deep endometriosis in different anatomical locations was reported. RESULTS Prevalence of ovarian endometrioma and/or deep endometriosis was 25% and of adenomyosis was 12%. Prevalence of endometrioma was 20% and of deep endometriosis was 9%, for each location being 8% in the bowel, 3% in the uterosacral ligaments, 3% in the rectovaginal septum and 0.5% in the urinary bladder. CONCLUSIONS In symptomatic women examined with transvaginal ultrasound by an experienced ultrasound examiner, ovarian endometrioma and/or deep endometriosis was found in one of four women and adenomyosis in one of nine women. Deep endometriosis was present in one of 11 women. Despite having symptoms, half of the women had no abnormal ultrasound findings.

Abstract
AbstractEndometriosis is a chronic gynecological disease characterized by the growth of functional ectopic endometrial glands and stroma outside the uterus. It causes pelvic pain, dysmenorrhea, dyspareunia, or infertility. Diagnosis requires a combination of clinical history, non-invasive and invasive techniques. The aim of the present review was to evaluate the contribution of imaging techniques, mainly transvaginal sonography and magnetic resonance imaging to diagnose different locations and for the most appropriate treatment planning. Endometriosis requires a multidisciplinary teamwork to manage these patients clinically and surgically.

Abstract
Background Up to 28% of endometriosis patients do not get pain relief from therapeutic laparoscopy but this subgroup is not defined. Objectives To identify any prognostic patient-specific factors (such as but not limited to patients’ type or location of endometriosis, sociodemographics and lifestyle) associated with a clinically meaningful reduction in post-surgical pain response to operative laparoscopic surgery for endometriosis. Search strategy PubMed, Cochrane and Embase databases were searched from inception to 19 May 2020 without language restrictions. Backward and forward citation tracking was used. Selection criteria, data collection and analysis: Cohort studies reporting prognostic factors, along with scores for domains of pain associated with endometriosis before and after surgery, were included. Studies that compared surgeries, or laboratory tests, or outcomes without stratification were excluded. Results were synthesised but variation in study designs and inconsistency of outcome reporting precluded us from doing a meta-analysis. Main results Five studies were included. Quality assessment using the Newcastle–Ottawa scale graded three studies as high, one as moderate and one as having a low risk of bias. Four of five included studies separately reported that a relationship exists between more severe endometriosis and stronger pain relief from laparoscopic surgery. Conclusion Currently, there are few studies of appropriate quality to answer the research question. We recommend future studies report core outcome sets to enable meta-analysis. Lay summary Endometriosis is a painful condition caused by displaced cells from the lining of the womb, causing inflammation and scarring inside the body. It affects 6–10% of women and there is no permanent cure. Medical and laparoscopic surgical treatments are available, but about 28% of patients do not get the hoped-for pain relief after surgery. Currently, there is no way of predicting who gets better and who does not. We systematically searched the world literature to establish who may get better, in order to improve counselling when women choose treatment options. We identified five studies of variable quality showing: More complex disease (in specialist hands) responds better to surgery than less, but more studies needed.

Abstract
Endometriosis, a common chronic inflammatory disease in female of reproductive age, is closely related to patient symptoms and fertility. Because of its high contrast resolution and objectivity, MRI can contribute to the early and accurate diagnosis of ovarian endometriotic cysts and deeply infiltrating endometriosis without the need for any invasive procedure or radiation exposure. The ovaries, which are the most frequent site of endometriosis, can be afflicted by multiple related conditions and diseases. For the diagnosis of deeply infiltrating endometriosis and secondary adhesions among pelvic organs, fibrosis around the ectopic endometrial gland is usually found as a T2 hypointense lesion. This review summarizes the MRI findings obtained for ovarian endometriotic cysts and their physiologically and pathologically related conditions. This article also includes the key imaging findings of deeply infiltrating endometriosis.

Abstract
Background Whilst some imaging signs of endometriosis are common and widely accepted as ‘typical’, a range of ‘subtle’ signs could be present in imaging studies, presenting an opportunity to the radiologist and the surgeon to aid the diagnosis and facilitate preoperative surgical planning. Objective To summarise and analyse the current information related to indirect and atypical signs of endometriosis by ultrasound (US) and magnetic resonance imaging (MRI). Methods Through the use of PubMed and Google scholar, we conducted a comprehensive review of available articles related to the diagnosis of indirect signs in transvaginal US and MRI. All abstracts were assessed and the studies were finally selected by two authors. Results Transvaginal US is a real time dynamic exploration, that can reach a sensitivity of 79-94% and specificity of 94%. It allows evaluation of normal sliding between structures in different compartments, searching for adhesions or fibrosis. MRI is an excellent tool that can reach a sensitivity of 94% and specificity of 77% and allows visualisation of the uterus, bowel loop deviation and peritoneal inclusion cysts. It also allows the categorisation and classification of ovarian cysts, rectovaginal and vesicovaginal septum obliteration, and small bowel endometriotic implants. Conclusion The use of an adequate mapping protocol with systematic evaluation and the reporting of direct and indirect signs of endometriosis is crucial for detailed and safe surgical planning.

Abstract
Background
Endometriosis is a challenging gynecological condition that has a profound influence on the quality of life of affected women. Transvaginal ultrasound is considered the first-line imaging method in preoperative assessment of the extent and severity of endometriosis. Accurate preoperative mapping can aid the surgeon in patient counselling, selection of the most appropriate surgical method that minimizes the operative and post-operative complications. The aim of our study is to evaluate the accuracy of transvaginal sonography (TVS) in precisely assessing the size, location and extent of deep infiltrating endometriosis (DIE) using a new modified endometriosis mapping proforma with histopathological confirmation. Our prospective observational study included 101 women with clinically suspected DIE who underwent TVS followed by laparoscopy from October 2018 to December 2020 with a maximum of 4 weeks interval. Precise mapping of DIE was done during TVS and laparoscopy. Results were correlated with histopathology findings.
Results
DIE was confirmed by histopathology in 88 patients. Sensitivity and specificity for individual DIE locations were rectovaginal septum 67.9% and 98.6%; vagina 52.2% and 98.7%; uterosacral ligaments 82.5% and 96.2%; torus 96.4% and 97.3%; parametrium 68.8% and 96.9%; rectum 100% and 98.8%; bladder 100% and 100%, ureters 63.4% and 99.0%; scar endometriosis 100% and 100%; pouch of Douglas obliteration 97.7% and 100%. No statistically significant difference was detected between ultrasound and histopathology size. Ultrasound tended to underestimate the lesion size; the underestimation was more pronounced for lesions > 3 cm. “Butterfly” and “tram-track” signs are two new sonographic signs related to posterior compartment DIE. No post-operative complications were recorded. There were no cases of DIE recurrence. Eleven out of 22 cases of infertility achieved pregnancy during 18 months follow-up.
Conclusion
TVS provides a thorough and accurate evaluation of the extent of endometriosis. An experienced radiologist can use E-PEP to provide an accurate demonstration of the location and extent of DIE which helps the surgeon select the most appropriate surgical approach ensuring radical treatment of the disease and minimizing short- and long-term complications.

Abstract
The role of hybrid imaging with 2-[18F] flourodeoxyglucose (FDG) positron emission tomography and computed tomography (PET/CT) is continuously evolving and now considered standard practice in evaluation of disease stage, treatment response, recurrent disease and follow-up for numerous primary malignancies. In gynecological malignancies FDG PET/CT plays an important role, not only in the assessment of disease in the pre-and post-therapy setting, but also in radiation therapy (RT) planning by defining the metabolically active gross tumor volume (GTV. The glucose analogue radiotracer, FDG, is by far the most utilized radiotracer in PET/CT and is typically seen with high uptake in malignant cells. The radiotracer FDG has a high sensitivity but low specificity for malignancy, as benign processes with an inflammatory response for example infection, are also FDG-avid. In the evaluation of the female pelvic region an awareness of potential confounding factors in the interpretation of FDG is essential as variations of FDG uptake occur in accordance with the menstrual cycle and the menopausal state. Incidental imaging findings in the female genital can pose differential diagnostic challenges as false-positive and false-negative findings in benign and malignant processes are not uncommon. Gynecological malignancies continue to pose major public health problems with cervical cancer as the fourth most common cancer in women ranking after breast cancer, colorectal cancer and lung cancer. Familiarity with frequently encountered benign and malignant variants and pitfalls in FDG PET/CT in the female pelvic region can aid the reader in differential diagnostic considerations.

Abstract
Imaging of endometriosis and in particular deep endometriosis (DE) is crucial in the clinical management of women facing this debilitating condition. Transvaginal sonography (TVS) is the first-line imaging method and magnetic resonance imaging (MRI) may provide supplemental information. However, the delay in diagnosis of up to 10 years and more is of concern. This problem might be overcome by simple steps using imaging with emphasis on TVS and referral to tertiary care. Finally, TVS is crucial in mapping extent and location of disease in planning surgical therapy and counseling women regarding various therapeutic options. This review presents the available data on imaging of endometriosis with a focus on TVS and MRI for DE, adenomyosis, and ovarian endometriomas including endometriomas in pregnancy as well as the use of "soft markers." The review presents an approach that is in accordance with the International Deep Endometriosis Analysis (IDEA) group consensus statement.

Abstract
OBJECTIVES The aim of this study was to evaluate the significance of a new imaging sign, the "cloverleaf sign," in diagnosing deep infiltrating endometriosis (DIE) with magnetic resonance imaging (MRI) in concordance to intraoperative findings. MATERIALS AND METHODS This retrospective study included 103 patients operated during the January 2016 to June 2018 period with preoperative 1.5 T and 3 T MRI, with or without vaginal and rectal gel filling. Magnetic resonance imaging scans were read blinded to intraoperative findings by a specialized gynecologic radiologist and a junior radiologist, and then compared with intraoperative findings by looking at the operation report, postoperative diagnosis, and intraoperative images and videos by an experienced gynecologist surgeon specialized in endometriosis surgery. All endometriosis lesions were confirmed by pathology. The "cloverleaf sign" was defined as a cloverleaf-like figure in imaging morphology; the "leaves" formed by at least 3 different organs come together in the center of the figure formed by constrictive adhesions including T2-weighted (T2W) hypointense DIE. Operation times, intraoperative blood loss, and the frequency of DIE and bowel resections were analyzed in cloverleaf and noncloverleaf groups. The 2-sample Wilcoxon rank-sum (Mann-Whitney U) test and multivariate analysis of variance were used to calculate the significance of an overall impact of cloverleaf sign on operation time, blood loss, and the amount of the bowel resection rate. P < 0.05 was considered statistically significant. RESULTS The prevalence of DIE in the study population was 79.6%. A total of 11.5% of the patients had no endometriosis, 32.6% had rASRM I and II, and 55.9% had rASRM III and IV. Forty-six patients (45%) had received rectal and vaginal gel opacification before scanning, 57 (55%) did not. A cloverleaf sign on MRI was detected in 34 patients (15 in gel filling and 19 in nonfilling group). The interreader agreement was almost perfect 0.91 (κ). The median operation time in the cloverleaf group was 248 minutes (interquartile range [IQR], 165-330) compared with 145 minutes in the noncloverleaf group (IQR, 90-210), that is, significantly higher (P < 0.001). Intraoperative blood loss was also significantly higher in the conglomerate group (125 vs 50 mL; IQR, 100-300 vs 50-100; P < 0.001). Of the bowel resections in our study population, 41% (14/34) were performed on patients with a cloverleaf sign in the MRI, compared with 13% (9/69) in patients without the cloverleaf sign. CONCLUSIONS The "cloverleaf" MRI sign was associated with significantly longer operation time, increased intraoperative blood loss, and higher rates of bowel resection in DIE patients.

Abstract
Endometriosis affects approximately 10% of reproductive age women and represents a significant cause of pelvic pain and infertility. Unfortunately, the diagnosis of endometriosis is often delayed by years. Endometriosis may manifest as cystic lesions in the ovaries known as endometriomas. Superficial endometriosis is typically detected by laparoscopy along the pelvic peritoneum as these lesions tend to be difficult to detect by imaging. Deep infiltrative endometriosis may be detected by ultrasound, CT or MRI in classic locations within the pelvis, such as the posterior cul-de-sac and uterosacral ligaments. Endometriosis may also involve the thorax, gastrointestinal and urinary tracts, and locations such as the abdominal wall and abdominal organs. We present MRI and CT case examples, together with corresponding laparoscopic and histopathology images to enhance radiologists' understanding of this disease.

Abstract
Endometriosis is often seen and sometimes initially diagnosed on hysterosalpingography (HSG), an imaging exam routinely performed on patients with infertility. Here we discuss the role of HSG in the evaluation of patients with infertility with a focus on patients with endometriosis. The HSG technique, including patient preparation as well as potential risks and complications, is detailed. Imaging findings in patients with endometriosis are illustrated and a template for exam reporting is presented. Common imaging pitfalls are described with examples.

Abstract
Postmenopausal endometriosis is an important clinical entity which is likely under-recognized and in which the Radiologist can play a valuable role. In this review, we describe the clinical presentation and management of postmenopausal endometriosis, appraising the literature and providing case examples. Persons with postmenopausal endometriosis may present with symptoms including pelvic pain or dyschezia, but endometriosis may also be an asymptomatic, incidental finding. Women may or may not have a prior history of endometriosis or a history of symptoms consistent with it. Therapies and conditions which increase exogenous or endogenous estrogen, respectively, increase the risk. Endometriosis can be found in different locations throughout the body, and the possibility of malignancy should be assessed, especially in the postmenopausal population, where age increases cancer risk. Treatment may involve surgery or medical interventions. Guidelines describing appropriate imaging surveillance in these patients are lacking. In the postmenopausal population, Radiologists need to consider endometriosis as a diagnosis, recommend appropriate exams such as MRI and US, and suggest endometriosis-associated malignancies when appropriate, based on classic morphologic features.

Abstract
Endometriosis is a common gynecologic disorder characterized by the presence of ectopic endometrial tissue outside the endometrial cavity. Magnetic Resonance Imaging (MRI) has become a mainstay for diagnosis and staging of this disease. In the literature, significant heterogeneity exists in the descriptions of imaging findings and anatomic sites of involvement. The Society of Abdominal Radiology's Endometriosis Disease-Focused Panel presents this consensus document to establish an MRI lexicon for endometriosis MRI evaluation and anatomic localization.

Abstract
Endovaginal sonographic imaging has been shown to reliably identify pelvic endometriosis, but most United States imaging practices do not adequately assess locations and features of endometriosis beyond ovarian endometrioma. In this article, we propose a protocol for sonographer-acquired images and maneuvers to be interpreted subsequently by sonologists (radiologists or gynecologists). The purpose is to improve the sensitivity of endovaginal sonography for the detection of endometriosis in imaging practices that involve the non-physician sonographer as part of their workflow.

Abstract
Endometriosis is a common benign gynecological condition defined as the presence of endometrial tissue located outside the uterus and frequently associated with chronic pelvic pain and infertility. It is a polymorphic disease that can be presented as superficial implants, endometriomas and deep lesions that infiltrate the peritoneal surface associated with fibrosis and inflammatory reaction. Diagnosis of deep endometriosis is difficult and delayed, frequently missed in a routine ultrasound. Transvaginal ultrasound is the first-line imaging modality to investigate endometriosis and when performed by an expert in female pelvic imaging can provide a reliable mapping of the affected sites. Bowel preparation can be used to improve the detection of bowel lesions as well as the other sites affected by eliminating artifacts. Surgery has been the mainstay to treat symptomatic endometriosis and preoperative imaging mapping is crucial for better results and to reduce residual disease. The goals of surgery include radical removal of all lesions and the restoration of normal pelvic anatomy. The author describes technical aspects and imaging interpretation of the transvaginal sonography to investigate deeply infiltrative endometriosis.

Abstract
PURPOSE To retrospectively investigate the relationship between ovarian positioning on pre-operative MR imaging and intra-operative staging of endometriosis. MATERIALS AND METHODS Sixty-five women with suspected endometriosis who underwent pre-operative MRI and subsequent intra-operative staging of endometriosis formed the study group. A trained senior radiology resident and a board-certified staff radiologist experienced in endometriosis reviewed MR images for ovarian positioning and the presence of an endometrioma. The position of the ovaries was classified as (a) kissing when they were posterior to the uterus and in contact, (b) retropositioned when they were posterior to the uterus but not in contact, or (c) normal. Intra-operative staging of endometriosis (stage 0 to IV) was determined using the revised American Society for Reproductive Medicine classification system (rASRM) by a surgeon with expertise in endometriosis surgery. Correlation between ovarian positioning and endometriosis stage was evaluated with a logistical regression analysis. Sensitivity, specificity, and accuracy were calculated. RESULTS MR images revealed kissing ovaries in 12 women, retropositioned ovaries in 17 women, and normally positioned ovaries in 36 women. At surgery, endometriosis stages 0, I, II, III, and IV were found in 13, 15, 6, 9, and 22 patients, respectively. The odds of stage IV endometriosis were eight times higher given kissing or retropositioned compared to normal ovaries, regardless of the presence of an endometrioma (p =0.01). Kissing and retropositioned ovaries had an accuracy of 82% for stage IV endometriosis, with 86% sensitivity and 79% specificity. All cases with kissing ovaries had stage III/IV endometriosis. CONCLUSIONS Kissing and retropositioned ovaries on pre-operative MR images are associated with higher intra-operative rASRM stages of endometriosis.

Abstract
OBJECTIVES The aim of this study was to evaluate the use of ultrasound (US) soft markers as a first-line imaging tool to raise suspicion of rectosigmoid (RS) involvement in women suspected of having deep endometriosis. METHODS We included in this prospective observational study all patients with clinical suspicion of deep endometriosis who underwent diagnostic transvaginal US evaluation at our unit from January 2016 to February 2017. Several US soft markers were evaluated for prediction of RS involvement (presence of US signs of uterine adenomyosis, presence of an endometrioma, adhesion of the ovary to the uterus (reduced ovarian mobility), presence of 'kissing ovaries' (KO) and absence of the 'sliding sign'), using as the gold standard expert US examination for the presence of RS endometriosis. RESULTS Included were 333 patients with clinical suspicion of deep endometriosis. Of these, 106 had an US diagnosis of RS endometriosis by an expert. The only significant variables found in the prediction model were absence of the sliding sign (odds ratio (OR), 13.95; 95% CI, 7.7-25.3), presence of KO (OR, 22.5; 95% CI, 4.1-124.0) and the interaction between these two variables (OR, 0.03; 95% CI, 0.004-0.28). Regarding their interaction, RS endometriosis was present when KO was absent and the sliding sign was present in 10% (19/190) of cases, when both KO and the sliding sign were present in 71.4% (5/7) of cases, when both KO and the sliding sign were absent in 60.8% (76/125) of cases and when KO was present and the sliding sign was absent in 54.5% (6/11) of cases. Thus, when the sliding sign was absent and/or KO was present, transvaginal US showed a specificity of 75% (95% CI, 69-80%) and a sensitivity of 82% (95% CI, 73-88%). CONCLUSIONS US findings of absence of the sliding sign and/or presence of KO in patients with clinical suspicion of endometriosis should raise suspicion of RS involvement and indicate referral for expert US examination, with a low rate of false-negative diagnosis.

Abstract
Objective We illustrate the magnetic resonance imaging (MRI) features of endometriosis. Background Endometriosis is a chronic gynaecological condition affecting women of reproductive age and may cause pelvic pain and infertility. It is characterized by the growth of functional ectopic endometrial glands and stroma outside the uterus and includes three different manifestations: ovarian endometriomas, peritoneal implants, deep pelvic endometriosis. The primary locations are in the pelvis; extrapelvic endometriosis may rarely occur. Diagnosis requires a combination of clinical history, invasive and non-invasive techniques. The definitive diagnosis is based on laparoscopy with histological confirmation. Diagnostic imaging is necessary for treatment planning. MRI is as a second-line technique after ultrasound. The MRI appearance of endometriotic lesions is variable and depends on the quantity and age of haemorrhage, the amount of endometrial cells, stroma, smooth muscle proliferation and fibrosis. The purpose of surgery is to achieve complete resection of all endometriotic lesions in the same operation. Conclusion Owing to the possibility to perform a complete assessment of all pelvic compartments at one time, MRI represents the best imaging technique for preoperative staging of endometriosis, in order to choose the more appropriate surgical approach and to plan a multidisciplinary team work. Teaching Points • Endometriosis includes ovarian endometriomas, peritoneal implants and deep pelvic endometriosis. • MRI is a second-line imaging technique after US. • Deep pelvic endometriosis is associated with chronic pelvic pain and infertility. • Endometriosis is characterized by considerable diagnostic delay. • MRI is the best imaging technique for preoperative staging of endometriosis.

Abstract
The IDEA (International Deep Endometriosis Analysis group) statement is a consensus opinion on terms, definitions and measurements that may be used to describe the sonographic features of the different phenotypes of endometriosis. Currently, it is difficult to compare results between published studies because authors use different terms when describing the same structures and anatomical locations. We hope that the terms and definitions suggested herein will be adopted in centers around the world. This would result in consistent use of nomenclature when describing the ultrasound location and extent of endometriosis. We believe that the standardization of terminology will allow meaningful comparisons between future studies in women with an ultrasound diagnosis of endometriosis and should facilitate multicenter research.

Abstract
BACKGROUND About 10% of women of reproductive age suffer from endometriosis. Endometriosis is a costly chronic disease that causes pelvic pain and subfertility. Laparoscopy, the gold standard diagnostic test for endometriosis, is expensive and carries surgical risks. Currently, no non-invasive tests that can be used to accurately diagnose endometriosis are available in clinical practice. This is the first review of diagnostic test accuracy of imaging tests for endometriosis that uses Cochrane methods to provide an update on the rapidly expanding literature in this field. OBJECTIVES • To provide estimates of the diagnostic accuracy of imaging modalities for the diagnosis of pelvic endometriosis, ovarian endometriosis and deeply infiltrating endometriosis (DIE) versus surgical diagnosis as a reference standard.• To describe performance of imaging tests for mapping of deep endometriotic lesions in the pelvis at specific anatomical sites.Imaging tests were evaluated as replacement tests for diagnostic surgery and as triage tests that would assist decision making regarding diagnostic surgery for endometriosis. SEARCH METHODS We searched the following databases to 20 April 2015: MEDLINE, CENTRAL, EMBASE, CINAHL, PsycINFO, Web of Science, LILACS, OAIster, TRIP, ClinicalTrials.gov, MEDION, DARE, and PubMed. Searches were not restricted to a particular study design or language nor to specific publication dates. The search strategy incorporated words in the title, abstracts, text words across the record and medical subject headings (MeSH). SELECTION CRITERIA We considered published peer-reviewed cross-sectional studies and randomised controlled trials of any size that included prospectively recruited women of reproductive age suspected of having one or more of the following target conditions: endometrioma, pelvic endometriosis, DIE or endometriotic lesions at specific intrapelvic anatomical locations. We included studies that compared the diagnostic test accuracy of one or more imaging modalities versus findings of surgical visualisation of endometriotic lesions. DATA COLLECTION AND ANALYSIS Two review authors independently collected and performed a quality assessment of data from each study. For each imaging test, data were classified as positive or negative for surgical detection of endometriosis, and sensitivity and specificity estimates were calculated. If two or more tests were evaluated in the same cohort, each was considered as a separate data set. We used the bivariate model to obtain pooled estimates of sensitivity and specificity when sufficient data sets were available. Predetermined criteria for a clinically useful imaging test to replace diagnostic surgery included sensitivity ≥ 94% and specificity ≥ 79%. Criteria for triage tests were set at sensitivity ≥ 95% and specificity ≥ 50%, ruling out the diagnosis with a negative result (SnNout test - if sensitivity is high, a negative test rules out pathology) or at sensitivity ≥ 50% with specificity ≥ 95%, ruling in the diagnosis with a positive result (SpPin test - if specificity is high, a positive test rules in pathology). MAIN RESULTS We included 49 studies involving 4807 women: 13 studies evaluated pelvic endometriosis, 10 endometriomas and 15 DIE, and 33 studies addressed endometriosis at specific anatomical sites. Most studies were of poor methodological quality. The most studied modalities were transvaginal ultrasound (TVUS) and magnetic resonance imaging (MRI), with outcome measures commonly demonstrating diversity in diagnostic estimates; however, sources of heterogeneity could not be reliably determined. No imaging test met the criteria for a replacement or triage test for detecting pelvic endometriosis, albeit TVUS approached the criteria for a SpPin triage test. For endometrioma, TVUS (eight studies, 765 participants; sensitivity 0.93 (95% confidence interval (CI) 0.87, 0.99), specificity 0.96 (95% CI 0.92, 0.99)) qualified as a SpPin triage test and approached the criteria for a replacement and SnNout triage test, whereas MRI (three studies, 179 participants; sensitivity 0.95 (95% CI 0.90, 1.00), specificity 0.91 (95% CI 0.86, 0.97)) met the criteria for a replacement and SnNout triage test and approached the criteria for a SpPin test. For DIE, TVUS (nine studies, 12 data sets, 934 participants; sensitivity 0.79 (95% CI 0.69, 0.89) and specificity 0.94 (95% CI 0.88, 1.00)) approached the criteria for a SpPin triage test, and MRI (six studies, seven data sets, 266 participants; sensitivity 0.94 (95% CI 0.90, 0.97), specificity 0.77 (95% CI 0.44, 1.00)) approached the criteria for a replacement and SnNout triage test. Other imaging tests assessed in small individual studies could not be statistically evaluated.TVUS met the criteria for a SpPin triage test in mapping DIE to uterosacral ligaments, rectovaginal septum, vaginal wall, pouch of Douglas (POD) and rectosigmoid. MRI met the criteria for a SpPin triage test for POD and vaginal and rectosigmoid endometriosis. Transrectal ultrasonography (TRUS) might qualify as a SpPin triage test for rectosigmoid involvement but could not be adequately assessed for other anatomical sites because heterogeneous data were scant. Multi-detector computerised tomography enema (MDCT-e) displayed the highest diagnostic performance for rectosigmoid and other bowel endometriosis and met the criteria for both SpPin and SnNout triage tests, but studies were too few to provide meaningful results.Diagnostic accuracies were higher for TVUS with bowel preparation (TVUS-BP) and rectal water contrast (RWC-TVS) and for 3.0TMRI than for conventional methods, although the paucity of studies precluded statistical evaluation. AUTHORS' CONCLUSIONS None of the evaluated imaging modalities were able to detect overall pelvic endometriosis with enough accuracy that they would be suggested to replace surgery. Specifically for endometrioma, TVUS qualified as a SpPin triage test. MRI displayed sufficient accuracy to suggest utility as a replacement test, but the data were too scant to permit meaningful conclusions. TVUS could be used clinically to identify additional anatomical sites of DIE compared with MRI, thus facilitating preoperative planning. Rectosigmoid endometriosis was the only site that could be accurately mapped by using TVUS, TRUS, MRI or MDCT-e. Studies evaluating recent advances in imaging modalities such as TVUS-BP, RWC-TVS, 3.0TMRI and MDCT-e were observed to have high diagnostic accuracies but were too few to allow prudent evaluation of their diagnostic role. In view of the low quality of most of the included studies, the findings of this review should be interpreted with caution. Future well-designed diagnostic studies undertaken to compare imaging tests for diagnostic test accuracy and costs are recommended.

Abstract
Endometriosis is a highly enigmatic disease with multiple presentations ranging from infertility to severe pain, often causing significant morbidity. Video-assisted laparoscopy (VALS) has now replaced laparotomy as the gold standard for the diagnosis and management of endometriosis. While imaging has a role in the evaluation of some patients, histologic examination is needed for a definitive diagnosis. Laboratory evaluation currently has a minor role in the diagnosis of endometriosis, although studies are underway investigating serum markers, genetic studies, and endometrial sampling. A high index of suspicion is essential to accurately diagnose this complex condition, and a multidisciplinary approach is often indicated. The following review discusses laparoscopic diagnosis of endometriosis from the pre-operative evaluation of patients suspected of having endometriosis to surgical technique for safe and adequate laparoscopic diagnosis of the condition and postsurgical care.

Abstract
Ultrasonography can detect ovarian endometriomas, but negative findings cannot exclude other localizations of endometriosis, especially in symptomatic patients. We describe a case of sudden development of large bilateral endometriomas after a series of negative ultrasound scans, causing bilateral hydronephrosis. Our patient is a 32-year-old nulligravida with long-lasting dysmenorrhea, urinary symptoms, and familiarity for endometriosis, who had voluntarily discontinued oral contraceptives. Various pelvic scans had not shown pathological findings. Five months following the last negative scan, she presented with pain and increase of abdominal girth. Ultrasonography and computed tomography showed large ovarian cysts (16 cm right - 10 cm left) and hydronephrosis bilaterally. She underwent conservative surgery followed by GnRH analogs. At a 6-months follow-up, she was symptom-free and ultrasonography showed no recurrence. Endometriosis has still an unknown mechanism of proliferation and its clinical behavior or progression is highly unpredictable. Severe uropathy is commonly related to direct ureteral involvement, but can also depend on an ab-extrinseco compression by large, rapidly growing endometriomas. Women at risk of endometriosis, who are not receiving empirical medical treatment, should be adequately and regularly assessed via pelvic ultrasonography and/or submitted to diagnostic laparoscopy in order to prevent serious consequences such as silent renal loss.

Abstract
Objective The purpose of this study is to assess the prevalence of abnormal CT findings in patients with surgically proven ruptured endometriotic cysts, as compared with those abnormal CT findings of ruptured ovarian functional cysts. Materials and Methods This study included 13 retrospectively identified patients with surgically confirmed ruptured ovarian endometriotic cysts and who had also undergone preoperative CT scanning during the previous seven years. As a comparative group, 25 cases of surgically confirmed ruptured ovarian functional cysts were included. We assessed the morphologic features of the cysts and the ancillary findings based on CT. Results For the endometriotic cysts, the mean maximum cyst diameter was significantly larger than that of the functional cysts (70.1 mm versus 36.4 mm, respectively, p < 0.05). The endometriotic cysts frequently had a multilocular shape and a thicker cyst wall, as compared to that of functional cysts, and these differences were statistically significant. Among the ancillary findings, endometriotic cysts showed a significantly higher prevalence of loculated ascites, ascites confined to the pelvic cavity without extension to the upper abdomen, and peritoneal strandings and infiltrations (p < 0.05). Although 11 of the 25 cases of functional cysts showed active extravasation of contrast material at the ovarian bleeding site, only one of 13 cases of endometriotic cysts showed active extravasation. Conclusion The diagnosis of ruptured endometriotic cyst should be suspected for a woman in whom CT reveals the presence of multilocular or bilateral ovarian cysts with a thick wall and loculated ascites confined to the pelvic cavity with pelvic fat infiltrations.
