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.

Objective To perform a systematic review of studies comparing the accuracy of transvaginal ultrasound (TVS) and magnetic resonance imaging (MRI) in diagnosing deep infiltrating endometriosis (DIE) including only studies in which patients underwent both techniques. Methods (LR+ and LR-) and diagnostic odds ratio (DOR).Results Of 375 citations identified, six studies (n = 424) were considered eligible. For MRI in the detection of DIE in the rectosigmoid, pooled sensitivity was 0.85 (95% CI, specificity was 0.95 (95% CI, LR+ was 18.4 (95% CI,, LRwas 0.16 (95% CI,. For TVS in the detection of DIE in the rectosigmoid, pooled sensitivity was 0.85 (95% CI, 0.68-0.94), specificity was 0.96 (95% CI, 0.85-0.99), LR+ was 20.4 (95% CI, 4.7-88.5), LR-was 0.16 (95% CI, 0.07-0.38) and DOR was 127 (95% CI, 14-1126 (95% CI, and DOR was 65 (95% CI,. For TVS in the detection of DIE in the rectovaginal septum, pooled sensitivity was 0.59 (95% CI, specificity was 0.97 (95% CI, LR+ was 23.5 (95% CI, and DOR was 56 (95% CI, . For TVS in the detection of DIE in the uterosacral ligaments, pooled sensitivity was 0.67 (95% CI, specificity was 0.86 (95% CI, LR+ was 4.8 (95% CI, LRwas 0.38 (95% CI,[7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24]

Objective To describe the clinical and ultrasound characteristics of uterine sarcomas. Methods This was a retrospective multicenter study. From the databases of 13 ultrasound centers, we identified patients with a histological diagnosis of uterine sarcoma with available ultrasound reports and ultrasound images who had undergone preoperative ultrasound examination between 1996 and 2016. As the first step, each author collected information from the original ultrasound reports from his/her own center on predefined ultrasound features of the tumors and by reviewing the ultrasound images to identify information on variables not described in the original report. As the second step, 16 ultrasound examiners reviewed the images electronically in a consensus meeting and described them using predetermined terminology. Results We identified 116 patients with leiomyosarcoma, 48 with endometrial stromal sarcoma and 31 with undifferentiated endometrial sarcoma. Median age of the patients was 56 years (range, 26–86 years). Most patients were symptomatic at diagnosis (164/183 (89.6%)), the most frequent presenting symptom being abnormal vaginal bleeding (91/183 (49.7%)). Patients with endometrial stromal sarcoma were younger than those with leiomyosarcoma and undifferentiated endometrial sarcoma (median age, 46 years vs 57 and 60 years, respectively). According to the assessment by the original ultrasound examiners, the median diameter of the largest tumor was 91 mm (range, 7–321 mm). Visible normal myometrium was reported in 149/195 (76.4%) cases, and 80.0% (156/195) of lesions were solitary. Most sarcomas (155/195 (79.5%)) were solid masses (> 80% solid tissue), and most manifested inhomogeneous echogenicity of the solid tissue (151/195 (77.4%)); one sarcoma was multilocular without solid components. Cystic areas were described in 87/195 (44.6%) tumors and most cyst cavities had irregular walls (67/87 (77.0%)). Internal shadowing was observed in 42/192 (21.9%) sarcomas and fan‐shaped shadowing in 4/192 (2.1%). Moderate or rich vascularization was found on color‐Doppler examination in 127/187 (67.9%) cases. In 153/195 (78.5%) sarcomas, the original ultrasound examiner suspected malignancy. Though there were some differences, the results of the first and second steps of the analysis were broadly similar. Conclusions Uterine sarcomas typically appear as solid masses with inhomogeneous echogenicity, sometimes with irregular cystic areas but only very occasionally with fan‐shaped shadowing. Most are moderately or very well vascularized. Copyright © 2019 ISUOG. Published by John Wiley & Sons Ltd.

Objective To establish the accuracy of three-dimensional ultrasound (3D-US), compared with magnetic resonance imaging (MRI), for diagnosing uterine anomalies, using the European Society of Human Reproduction and Embryology-European Society for Gynaecological Endoscopy (ESHRE-ESGE) consensus on the classification of congenital anomalies of the female genital tract.

What are the novel findings of this work? This is the first prospective multicenter study evaluating the International Endometrium Tumor Analysis (IETA) terms and definitions in women with abnormal uterine bleeding, before and after menopause. Both unenhanced sonography and fluid-instillation sonography were evaluated and compared with histology. What are the clinical implications of this work? Our study provides didactic, evidence-based data on the sonographic findings of the normal and abnormal endometrium. This will help clinicians in the diagnosis of malignant as well as benign endometrial pathology. We also describe some easy-to-assess features which, when detected, make endometrial cancer very unlikely.

Our results seem to suggest that there is a statistically significant difference between 2DUS and MRI for the intestinal location of deep infiltrating endometriosis, whereas no differences were found among the techniques for the other locations.
