ABSTRACT
OBJECTIVE: To compare clinical and sonographic features of benign, borderline, and malignant invasive mucinous ovarian tumors (MOTs). MATERIALS AND METHODS: Retrospective observational multicenter study comprising 365 women (mean age: 46.1 years) with a histologically confirmed benign, borderline or malignant invasive MOT. Clinical data (patient's age, patient's complaints), tumor markers (CA-125 and CA-1 9.9), and sonographic data (tumor size, bilaterality, morphology -unilocular, multilocular, unilocular-solid, multilocular-solid and solid-, and IOTA color score) were reviewed and compared among these three groups. Women with ultrasound evidence on intra-abdominal disease spread were excluded. RESULTS: Three hundred seventy-eight MOTs (14 women had bilateral lesions) were analyzed. Histologically, 287 tumors were benign, 51 were borderline, and 40 were malignant. No difference in patient's mean age was observed. Women with borderline or invasive tumors were less frequently asymptomatic. Tumors were larger in case of invasive lesions. Borderline and invasive tumors showed solid components and exhibited IOTA color score 3 or 4, more frequently than benign lesions (p < 0.001). However, the authors discovered that 16 out of 51 (31.4%) of borderline tumors and six out of 40 (15.0%) of invasive cancers had no solid components and a color score 1 or 2, and were considered as a benign lesion by the sonolo- gist. On the other hand, 96 out of 287 (33.4%) benign mucinous cystadenoma exhibited solid components and/or a color score of 3 or 4. CONCLUSIONS: In spite of statistical differences, the authors observed significant overlapping in ultrasound features among benign, borderline, and invasive ovarian mucinous tumors that renders a difficult accurate preoperative discrimination among these lesions.

OBJECTIVE: To assess the diagnostic performance of a three-step strategy proposed by the International Ovarian Tumor Analysis (IOTA) Group for discriminating between benign and malignant adnexal masses. METHODS: This was a prospective observational study, performed at two tertiary-care university hospitals, of women diagnosed with an adnexal mass on transvaginal or transabdominal ultrasound between December 2012 and December 2014. Women were scheduled for an ultrasound evaluation, which was initially performed by non-expert examiners. The examiner had to classify the mass using 'simple descriptors' (first step) and, if not possible, using 'simple rules' (second step). For inconclusive masses, an expert examiner classified the mass according to their subjective impression (third step). Masses were managed expectantly, with serial follow-up examinations, or surgically, according to ultrasound findings and clinical symptoms. Histology was used as the reference standard. Masses that were managed expectantly with at least 1 year of follow-up were considered as benign for analytical purposes. Women with less than 1 year of follow-up were not included in the study. RESULTS: Six hundred and sixty-six women were included (median age, 41 (range, 18-81) years) of whom 514 were premenopausal and 152 were postmenopausal. Based on the three-step strategy, 362 women had surgical removal of the mass (53 malignant and 309 benign), 71 masses resolved spontaneously and 233 persisted. Four hundred and forty-eight (67.3%) of 666 masses could be classified using simple descriptors and, of the 218 that could not, 147 (67.4%) were classified using simple rules. Of the remaining 71 masses, the expert examiner classified 45 as benign, 12 as malignant and 14 as uncertain. Overall sensitivity, specificity, positive likelihood ratio and negative likelihood ratio of the three-step strategy were 94.3%, 94.9%, 18.6 and 0.06, respectively. CONCLUSION: The IOTA three-step strategy, based on the sequential use of simple descriptors, simple rules and expert evaluation, performs well for classifying adnexal masses as benign or malignant.

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. METHODS: Sixty women with uterine anomalies suspected after examination by conventional two-dimensional ultrasound were evaluated with 3D-US and MRI. These data were analyzed retrospectively to confirm the presence and type of uterine malformation in accordance with the ESHRE-ESGE consensus. Sensitivity, specificity and positive (PPV) and negative (NPV) predictive values were calculated, using MRI as the gold standard, and agreement between the two methods was evaluated by kappa index. RESULTS: Compared with MRI, for the diagnosis of normal uteri, 3D-US had a sensitivity of 83.3%, specificity of 100%, PPV of 100%, NPV of 98.2% and kappa index of 0.900. For dysmorphic uteri and for hemi-uteri, the sensitivity, specificity, PPV and NPV were all 100%, and kappa was 1.00. For septate uteri, the sensitivity was 100%, specificity was 88.9%, PPV was 95.5%, NPV was 100% and kappa was 0.918. For bicorporeal uteri, the sensitivity was 83.3%, specificity was 100%, PPV was 100%, NPV was 98.2% and kappa was 0.900. CONCLUSIONS: 3D-US is highly accurate for diagnosing uterine malformations, having a good level of agreement with MRI in the classification of different anomaly types based on the ESHRE-ESGE consensus.

OBJECTIVE: To determine the diagnostic performance of International Ovarian Tumor Analysis (IOTA) 'simple' rules for discriminating between benign and malignant adnexal masses. METHODS: A prospective study was performed between January 2011 and June 2012. Eligible patients were women diagnosed with a persistent adnexal mass who presented to the participating centers. Four trainees evaluated the adnexal mass by transvaginal ultrasound under the supervision of an expert examiner. The trainee analyzed the mass according to IOTA simple rules and provided a diagnosis of benign, malignant or inconclusive. All women included in the study underwent surgery and tumor removal in the center of recruitment. Diagnostic performance was assessed by calculating sensitivity, specificity and positive (LR+) and negative (LR-) likelihood ratios. RESULTS: A total of 340 women were included (mean patient age, 42.1 (range, 13-79) years). Of the tumors, 55 (16.2%) were malignant and 285 (83.8%) were benign. The IOTA simple rules could be applied in 270 (79.4%) cases. In these cases, sensitivity was 87.9% (95% CI, 72.4-95.2), specificity 97.5% (95% CI, 94.6-98.8), LR+ 34.7 (95% CI, 15.6-77.3) and LR- 0.12 (95% CI, 0.05-0.31). CONCLUSIONS: Application of the IOTA simple rules yielded acceptable results in terms of specificity in the hands of non-expert examiners. However, with non-expert examiners there was a 12% false-negative rate, which is relatively high.

OBJECTIVE: To describe the gray-scale and color Doppler ultrasound features as well as some clinical and biochemical features of metastatic ovarian tumors according to the origin of the primary tumor in a large study population, METHODS: This was a retrospective analysis of 116 masses in 92 patients (mean age, 51 years) evaluated and treated at three European university centers for a metastatic tumor in the ovary. All patients had undergone transvaginal color Doppler ultrasound according to a standardized protocol prior to surgery and tumor removal. Ultrasound features analyzed were bilaterality, tumor volume, morphologic gray-scale appearance and color score. CA 125 was also recorded. RESULTS: Primary tumor histological diagnosis was as follows: colon-sigmoid (n = 32), stomach (n = 28), breast (n = 20), uterus (n = 17), lymphoma (n = 4), liver-pancreas-biliary tract (n = 4) and miscellaneous (n = 11). There were no differences in age, menopausal status or CA 125 values according to origin of primary tumor. Bilaterality was significantly more frequent in stomach metastases (56%) in comparison with colon-sigmoid and liver-pancreas-biliary tract metastases (18.5% and 0%, respectively, P < 0.05). Median tumor volume was significantly lower in breast metastases (33.5 mL) compared with other metastases (P < 0.05) except stomach metastases and metastatic tumors from the miscellaneous group. Ovarian metastases from breast cancers were significantly more frequently solid in comparison to stomach, colorectal and uterine cancer metastases (95.0% vs. 60.8%, 46.8% and 70.6%, respectively, P < 0.05), and tended to appear moderately or highly vascularized. There were no differences in color score among all groups, although the percentage of masses with abundant color was high (50-82%). CONCLUSIONS: Ovarian metastases derived from breast cancers tend to be small, solid and vascularized; they seem to be the only ovarian metastases whose primary tumor origin can be suspected by ultrasonography preoperatively. Color score does not seem to help suspect the origin of the primary tumor.

A case of minimal deviation adenocarcinoma of the cervix in a 34-year-old female is presented. The ultrasonographic and three-dimensional power Doppler color studies revealed a nodular cervical lesion with vascularization more prominent in the center of the nodule but also present at the periphery. The imaging diagnosis was suggestive of a myoma but with more vascularization than a conventional one.

BACKGROUND: Cesarean section scar pregnancy is the rarest form of ectopic pregnancy and the most dangerous due to the high risk of uterine rupture and hemorrhage. CASE: We present two case reports of women diagnosed with an ectopic cesarean scar pregnancy. We performed conservative treatment because both patients desired fertility preservation. The first case was treated with laparoscopy and hysteroscopy simultaneously. For the second case the treatment started with an ultrasound-guided injection of methotrexate. Surgical laparoscopy and hysteroscopy were subsequently performed simultaneously. Four months later, the first woman had a spontaneous singleton pregnancy. An elective cesarean was performed. CONCLUSION: In these two case reports we have presented our experience with endoscopic surgery in the management of two patients who had a cesarean scar pregnancy and desired to preserve their fertility.

It is essential to deposit embryos as gently as possible during IVF, avoiding manoeuvres that might trigger uterine contractions which could adversely affect the results of this treatment. The time during which the embryo transfer catheter remains in the cervical canal might be related to stimulation of contractions. This study investigates the influence that the time interval before withdrawal of the catheter after ultrasound (US)-guided embryo deposit might have on the pregnancy rate in patients under IVF cycles. A total of 100 women about to undergo transfer of at least two optimal embryos was studied. The women were prospectively randomized into two groups: (i) slow withdrawal of the catheter immediately after embryo deposit (n = 51); and (ii) a 30 s delay before catheter withdrawal (n = 49). The pregnancy rates for transfer in the two groups were 60.8 and 69.4% respectively, with no significant differences. There were no statistically significant differences in pregnancy rates between the two patient groups. The results indicate either that the waiting interval was insufficient to detect differences, or that the retention time before withdrawing the catheter is not a factor that influences pregnancy rate.

Between October 1998 and January 1999, we examined the influence of ultrasound guidance in embryo transfer on pregnancy rate in 362 patients from our in-vitro fertilization (IVF)-embryo transfer programme. These patients were prospectively randomized into two groups: 182 had ultrasound-guided embryo replacement, and 180 had clinical touch embryo transfer. There were no statistically significant differences between the two groups with respect to age, cause of infertility and in the characteristics of the IVF cycle. The pregnancy rate was significantly higher among the ultrasound-guided embryo transfer group (50%) compared with the clinical touch group (33.7%) (P < 0.002). Furthermore, there was also a significant increase in the implantation rate: 25.3% in the ultrasound group compared with 18.1% in the clinical touch group (P < 0.05). In conclusion, ultrasound assistance in embryo transfer significantly improved pregnancy and implantation rates in IVF.

Knowledge of the nature of ovarian lesions is important in order to establish the correct treatment and, especially, to detect ovarian cysts that do not require surgical treatment. With the purpose of demonstrating the utility of transvaginal sonography with colour Doppler of ovarian functional ovarian cysts, 378 ovarian tumours were studied, comparing sonographic diagnosis with pathological findings. Sensitivity and specificity of colour Doppler transvaginal sonography to detect functional ovarian cysts were 84.6 and 99.2% respectively. Positive and negative predictive values were 98 and 93.5% respectively. In our experience, transvaginal sonography with colour Doppler is a useful technique in the diagnosis of ovarian pathology.

Techniques of oocyte retrieval have progressed from laparoscopy to transvaginal follicular aspiration under ultrasonographic control. This highly efficient method, routinely used nowadays, is not free of complications. We present a case of a ureteral lesion secondary to vaginal ultrasound follicular puncture for oocyte recovery in in-vitro fertilization. Despite the surgical procedure to reimplant the ureter, the patient achieved a twin pregnancy which is ongoing uneventfully.
