BACKGROUND
CA125 is the most used tumor marker for ovarian cancer monitoring and diagnosis. This study aimed to evaluate the capacity to predict malignancy in women with adnexal tumors using CA125 measurement and ultrasound criteria before the pathological examination.
MATERIALS AND METHODS
This observational diagnostic study was conducted on 300 patients with obvious diagnosis of adnexal mass consists of ovarian masses, fallopian tubes, and masses within the broad ligament referring to Alzahra and Beheshti Hospitals from 2018 to 2019. Ultrasound examinations were done before surgery and malignancy risk was investigated by the ADNEX criterion. Sensitivity, specificity, positive and negative likelihood ratio (likelihood ratio [LR]+ and LR-), and area under the curve (AUC) were calculated.
RESULTS
From 284 patients, 260 masses were categorized in benign, 18 were in borderline, and 18 masses were malignant. The mean age of patients with malignant tumors was significantly higher than the others ( = 0.01). Differences in the level of CA-125 were not statistically significant ( = 0.78). Furthermore, the proportion of ascites in the malignant group (16.3%) was significantly higher than the others ( = 0.003). The AUC in ADNEX model (cutoff ≥9%) for differentiation of benign and malignant tumors was 0.75 (95% confidence interval [CI]: 0.69-0.80) with a sensitivity of 0.63 (95% CI: 0.41-0.81) and a specificity of 0.80 (95% CI: 0.74-0.84). Receiver operating characteristic analysis for CA-125 revealed that this variable is not capable for discrimination between benign and malignant tumors as the AUCs of the aforementioned variable were 0.60, 0.60, and 0.52 for the whole patients, premenopause, and postmenopause categories.
CONCLUSION
CA-125 marker, along with other ultrasound findings, can be more accurate in identifying the malignancy of the adnexa tumor.

BACKGROUND
The composition of pelvic masses during pregnancy is complex, and over >70% of masses are physiology. Determining the source and nature of tumor tissue is incredibly important in clinical practice, as the proportion of metastatic and low-grade tumors in adnexal masses increase during pregnancy. This study sought to analyze the pathological features of persistent adnexal masses in pregnancy.
METHODS
A retrospective case analysis method was adopted to summarize the pathologic features of persistent adnexal masses in pregnancy in 228 patients at the Beijing Chao-Yang Hospital, Capital Medical University.
RESULTS
Mature teratoma was the most common histopathological type of persistent adnexal masses in pregnancy (66/228, 28.95%), followed by the corpus luteum of pregnancy (38/228, 16.67%). Borderline/malignant tumors accounted for 5.70% (13/228) of tumors. Malignant adnexal tumor tissues were derived from multiple types of tissues. a single-factor analysis showed that borderline/malignant tumors had a significant relationship with the morphological features of mass in the ultrasound (P=0.000), and had a significant relationship with initial mass size (P=0.018). A multivariate binary logistic regression analysis indicated no certain independent risk factor. A significant difference in tumor pathology distribution was noted between those who underwent emergency surgery during pregnancy, elective surgery during pregnancy, and simultaneous tumor removal during cesarean section (χ=24.22, P=0.000).
CONCLUSIONS
A special particularity exists in the pathology distribution of persistent adnexal masses in pregnancy. Additionally, extensive histological sources and the need to rule out borderline/malignancy for solid cystic tumors were noted.

BACKGROUND
Quantitative contrast-enhanced ultrasonography parameters are affected by various factors. We evaluated corrected quantitative contrast enhanced ultrasonography in differentiating benign adnexal tumors from malignant tumors.
METHODS
Patients with adnexal masses who underwent conventional and contrast-enhanced ultrasonography were included. Contrast-enhanced ultrasonography parameters such as base intensity, arrival time, peak intensity, time to peak intensity, ascending slope, and descending slope were measured. Corrected (time to peak intensity - arrival time) (time to peak intensity - arrival time) and (peak intensity - base intensity) (peak intensity - base intensity) were calculated. Lesions were confirmed by pathologic examination of surgical specimens.
RESULTS
This study included 31 patients with 35 adnexal lesions including 20 (57.10%) benign and 15 (42.90%) malignant lesions. The corrected contrast-enhanced ultrasonography quantitative parameters in lesions were statistically different between malignant and benign groups (<0.05). The optimal cut-off value for (time to peak intensity - arrival time) /(time to peak intensity - arrival time) , ascending slope, and (peak intensity - base intensity) /(peak intensity - base intensity) , and descending slope for differentiating malignant adnexal masses from benign tumors were 1.05 (area under curve: 0.93,<0.05), 1.11 (area under curve: 0.83, <0.05), 0.82 (area under curve: 0.73, <0.05), and -0.27 (area under curve: 0.66, =0.16), with sensitivity and specificity of 93.33% and 85.00%, 86.67% and 75.00%, 86.67% and 60.00%, and 54.55% and 66.67%, respectively.
CONCLUSIONS
Corrected contrast-enhanced ultrasonography parameters provide practical differential diagnosis value of adnexal lesions with high reliability for sonologists.

Ultrasound-based models exist to support the classification of adnexal masses but are subjective and rely upon ultrasound expertise. We aimed to develop an end-to-end machine learning (ML) model capable of automating the classification of adnexal masses. In this retrospective study, transvaginal ultrasound scan images with linked diagnoses (ultrasound subjective assessment or histology) were extracted and segmented from Imperial College Healthcare, UK (ICH development dataset; n = 577 masses; 1444 images) and Morgagni-Pierantoni Hospital, Italy (MPH external dataset; n = 184 masses; 476 images). A segmentation and classification model was developed using convolutional neural networks and traditional radiomics features. Dice surface coefficient (DICE) was used to measure segmentation performance and area under the ROC curve (AUC), F1-score and recall for classification performance. The ICH and MPH datasets had a median age of 45 (IQR 35-60) and 48 (IQR 38-57) years old and consisted of 23.1% and 31.5% malignant cases, respectively. The best segmentation model achieved a DICE score of 0.85 ± 0.01, 0.88 ± 0.01 and 0.85 ± 0.01 in the ICH training, ICH validation and MPH test sets. The best classification model achieved a recall of 1.00 and F1-score of 0.88 (AUC:0.93), 0.94 (AUC:0.89) and 0.83 (AUC:0.90) in the ICH training, ICH validation and MPH test sets, respectively. We have developed an end-to-end radiomics-based model capable of adnexal mass segmentation and classification, with a comparable predictive performance (AUC 0.90) to the published performance of expert subjective assessment (gold standard), and current risk models. Further prospective evaluation of the classification performance of this ML model against existing methods is required.

Review
Ovarian torsion is defined as twisting of the ovary around an axis consisting of its vascular pedicle, the infundibulopelvic ligament and the tubo-ovarian ligament, and can occur in females of any age. Torsion can be a result of ovarian mass causing asymmetry and subsequent torsion, or can be spontaneous. While ovarian torsion is a surgical emergency, early diagnosis and treatment can preserve ovarian viability even if necrosis is seen operatively. Presentation classically involves sudden onset severe abdominal pain and vomiting but diagnostic delay can follow subtler presentations. Diagnosis is most commonly based on sonographic findings, but advanced imaging such as CT or MRI may be required if sonography is not diagnostic. Treatment is surgical, with ovarian preservation preferred in almost all cases. In this review, I present the most recent evidence on epidemiology, diagnosis, and management of pediatric ovarian torsion, with a focus on point-of-care ultrasound for the emergency care provider.

Meta-Analysis Review
OBJECTIVE
To evaluate the diagnostic accuracy of different ultrasound signs for diagnosing adnexal torsion, using surgery as the reference standard.
METHODS
This was a systematic review and meta-analysis of studies published between January 1990 and November 2021 evaluating ovarian edema, adnexal mass, ovarian Doppler flow findings, the whirlpool sign and pelvic fluid as ultrasound signs (index tests) for detecting adnexal torsion, using surgical findings as the reference standard. The search for studies was performed in PubMed/MEDLINE, CINAHL, Scopus, The Cochrane Library, ClinicalTrials.gov and Web of Science databases. The Quality Assessment of Diagnostic Accuracy Studies-2 (QUADAS-2) tool was used to evaluate the quality of the studies. Pooled sensitivity, specificity, and positive and negative likelihood ratios were calculated separately, and the post-test probability of adnexal torsion following a positive or negative test was also determined.
RESULTS
The search identified 1267 citations after excluding duplicates. Eighteen studies were ultimately included in the qualitative and quantitative syntheses. Eight studies (809 patients) analyzed the presence of ovarian edema, eight studies (1044 patients) analyzed the presence of an adnexal mass, 14 studies (1742 patients) analyzed ovarian Doppler flow, six studies (545 patients) analyzed the whirlpool sign and seven studies (981 patients) analyzed the presence of pelvic fluid as ultrasound signs of adnexal torsion. Overall, the quality of most studies was considered to be moderate or good. However, there was a high risk of bias in the patient-selection and index-text domains (with the exception of the whirlpool sign) in a significant proportion of studies. Pooled sensitivity, specificity, and positive and negative likelihood ratios of each ultrasound sign were 58%, 86%, 4.0 and 0.49 for ovarian edema, 69%, 46%, 1.3 and 0.67 for adnexal mass, 65%, 91%, 7.6 and 0.38 for the whirlpool sign, 53%, 95%, 11.0 and 0.49 for ovarian Doppler findings and 55%, 69%, 1.7 and 0.66 for pelvic fluid. Heterogeneity was high for all analyses.
CONCLUSIONS
The presence of an adnexal mass or pelvic fluid have poor diagnostic accuracy as ultrasound signs of adnexal torsion, while the presence of ovarian edema, the whirlpool sign and decreased or absent ovarian Doppler flow have good specificity but moderate sensitivity for detecting adnexal torsion. © 2022 The Authors.

Review
In this study, we aimed to systematicallyreview the current evidence regarding the diagnostic accuracy of ultrasound in assessing adnexal masses in pregnancy. The Cochrane Register of Controlled Trials, PubMed, and EMBASE databases were searched for all types of clinical studies that utilised ultrasound for the diagnosis of adnexal masses in pregnancy. Only studies that used outcome measures of either histological diagnosis or significant regression of the adnexal mass on imaging follow-up were included. The quality of each study was assessed for risk of bias. The diagnostic performance of ultrasound in each study type was calculated, along with the pooled diagnostic performance of ultrasound in differentiating benign from malignant masses. The initial search yielded 4,915 articles, of which 2,547 qualified for abstract screening. A total of 83 articles were included in this review, including one prospective cohort study, six retrospective observational studies, seven case series, and 69 case reports. In the included studies, the total number of adnexal masses was 559. The mean patient age was 29.2 years (95% confidence interval [CI]: 28.7-29.7), with a mean gestational age at diagnosis of 13.8 weeks (95% CI: 13.2-14.4). The mean quality assessment score was 75%. The International Ovarian Tumour Analysis Simple Rules were used in two articles, whereas subjective impression was used in the remaining 81 articles. The most frequently diagnosed mass was a simple or physiological cyst (35%). The prevalence of malignancy in the entire sample was 46/559 (8%; 95% CI: 34-61%). The overall pooled sensitivity, specificity, positive likelihood ratio, and negative likelihood ratio of ultrasound in detecting ovarian malignancy were 64% (95% CI: 30-88%), 88% (95% CI: 64-97%), 5.6 (95% CI: 1.2-25.4), and 0.4 (95% CI: 0.15-1), respectively. In conclusion, currently, there is a lack of high-quality prospective studies to guide the management of adnexal masses in pregnancy. Ultrasound appears to have an adequate accuracy in differentiating benign from malignant masses; however, more research is required to assess the role of ultrasound models, rules, and subjective assessment in pregnancy compared to non-pregnant women.

An adnexal mass is a common gynecological finding. Most adnexal masses are benign neoplasms, especially in premenopausal women. Yet, here we report a premenopausal woman with an adnexal mass that turned out to be an ovarian metastasis from colon cancer. This case emphasizes the importance of considering an ovarian metastasis in patients with (partially) solid adnexal masses and low serum CA125 levels. In addition, we identified the same mutation in the biopsied liver metastasis and resected right ovarian metastasis. This is in accordance with a previous molecular study of matched tumor pairs/trios of colorectal cancer patients with ovarian metastases, suggesting that mutated is a universal driver of the metastatic disease in women with -mutated colorectal cancer with ovarian metastases. More than half of all colorectal cancer patients with ovarian metastases harbor mutations. Future studies may investigate the efficacy of KRAS inhibitors in the treatment of these patients.

OBJECTIVE
Previous work has suggested that the ultrasound-based benign simple descriptors (BDs) can reliably exclude malignancy in a large proportion of women presenting with an adnexal mass. This study aimed to validate a modified version of the BDs and to validate a two-step strategy to estimate the risk of malignancy, in which the modified BDs are followed by the Assessment of Different NEoplasias in the adneXa (ADNEX) model if modified BDs do not apply.
METHODS
This was a retrospective analysis using data from the 2-year interim analysis of the International Ovarian Tumor Analysis (IOTA) Phase-5 study, in which consecutive patients with at least one adnexal mass were recruited irrespective of subsequent management (conservative or surgery). The main outcome was classification of tumors as benign or malignant, based on histology or on clinical and ultrasound information during 1 year of follow-up. Multiple imputation was used when outcome based on follow-up was uncertain according to predefined criteria.
RESULTS
A total of 8519 patients were recruited at 36 centers between 2012 and 2015. We excluded patients who were already in follow-up at recruitment and all patients from 19 centers that did not fulfil our criteria for good-quality surgical and follow-up data, leaving 4905 patients across 17 centers for statistical analysis. Overall, 3441 (70%) tumors were benign, 978 (20%) malignant and 486 (10%) uncertain. The modified BDs were applicable in 1798/4905 (37%) tumors, of which 1786 (99.3%) were benign. The two-step strategy based on ADNEX without CA125 had an area under the receiver-operating-characteristics curve (AUC) of 0.94 (95% CI, 0.92-0.96). The risk of malignancy was slightly underestimated, but calibration varied between centers. A sensitivity analysis in which we expanded the definition of uncertain outcome resulted in 1419 (29%) tumors with uncertain outcome and an AUC of the two-step strategy without CA125 of 0.93 (95% CI, 0.91-0.95).
CONCLUSION
A large proportion of adnexal masses can be classified as benign by the modified BDs. For the remaining masses, the ADNEX model can be used to estimate the risk of malignancy. This two-step strategy is convenient for clinical use. © 2022 The Authors.

While Non-Hodgkin Lymphoma (NHL) often involves the ovaries at time of autopsy, it is rarely present at the time of diagnosis. Here we present a case of a 20-year-old who presented with a large adnexal mass and elevated B-HCG, CA-125, and LDH. The patient underwent exploratory laparotomy, and frozen section of the left ovarian mass was suspected to be a dysgerminoma. Final pathologic diagnosis was Ann Arbor stage IVE Diffuse Large B-Cell Lymphoma, germinal center subtype. Patient is currently undergoing chemotherapy and has received the 3 of a planned 6 cycles of R-CHOP.
