Assessment of the performance of the O-RADS MRI score for the evaluation of adnexal masses, with technical notes / Desempenho do escore O-RADS RM para avaliação de massas anexiais, com notas técnicas

Abstract Objective: To assess the performance of the Ovarian-Adnexal Reporting and Data System Magnetic Resonance Imaging (O-RADS MRI) score in the evaluation of adnexal masses and to provide technical notes about its current MRI parameters and concepts. Materials and Methods: This was a prospective study of 226 patients with 287 adnexal masses (190 submitted to surgery or biopsy and 97 followed for at least one year). We calculated the sensitivity, specificity, positive predictive value, and negative predictive value for the O-RADS MRI score, using ≥ 4 as the cutoff for malignancy. We performed a technical analysis of the main updates to the score, announced in September 2020 by the American College of Radiology, in comparison with the original (2013) version. Results: We found that an O-RADS MRI score of 4 or 5 was associated with malignancy of an adnexal mass, with a sensitivity of 91.11% (95% CI: 83.23-96.08), specificity of 94.92% (95% CI: 90.86-97.54), positive predictive value of 89.13% (95% CI: 81.71-93.77), negative predictive value of 95.90% (95% CI: 92.34-97.84), and overall accuracy of 93.73% (95% CI: 90.27-96.24). Conclusion: Our findings support the use of the O-RADS MRI score for evaluating adnexal masses, especially those considered indeterminate on ultrasound. The updates made recently to the O-RADS MRI score facilitate its interpretation and will allow its more widespread use, with no loss of diagnostic accuracy.

Reproducibility study of Ovarian-Adnexal Reporting and Data System in describing adnexal masses / 中华超声影像学杂志

Objective:To investigate the intra- and inter-observer agreements of different experiencers using the Ovaria-adnexal Reporting and Data System (O-RADS) in the evaluation of adnexal masses.Methods:Totally 48 patients with adnexal masses (48 masses, mean size 9.5±4.7 cm, range 2.3-18.6 cm) found by ultrasound examination in the Third Affiliated Hospital of Sun Yat-sen University, from May 2019 to March 2020 were retrospectively analyzed. All the masses were confirmed by pathology or surgery. Four observers were divided into 2 senior doctors (Doctor 1 and Doctor 2) and 2 junior doctors (Doctor 3 and Doctor 4). Each observer independently evaluated adnexal masses twice using ultrasound O-RADS before and after systematic training, with an interval of 60 days. The intra-observer and inter-observer agreements were analyzed before and after training.Results:The inter-observer agreement between senior doctors were both excellent before and after systematic training (weight Kappa: 0.833 vs 0.802, percentage of agreement: 83.3% vs 81.3%). Whereas there was difference in the inter-observer agreement between non-experienced observers before and after training (weight Kappa: 0.399 vs 0.824, percentage of agreement: 50.0% vs 77.1%). After training, inter-observer agreement between junior doctors was significantly improved and comparable to senior (weight Kappa: 0.824 vs 0.802, percentage of agreement: 77.1% vs 81.3%). Before and after systematic training, the intra-observer agreements of the same doctor, the senior physicians were better than the junior (weight Kappa: 0.882 and 0.843 vs 0.440 and 0.605; percentage of agreement: 87.5% and 83.3% vs 58.3% and 54.2%).Conclusions:O-RADS risk classification system is a highly reproducible method in the subjective assessment of an adnexal mass among observers with varying levels of expertise. However, systematic training before clinical application is necessary and effective for non-experienced observers.

Clinical management of incidental findings on pelvic adnexal masses / Manejo clínico dos achados incidentais de massas pélvicas anexiais

Summary Due to widespread use of pelvic and transvaginal ultrasound in routine gynecological evaluation, the incidental finding of adnexal masses has led to discussions about management in asymptomatic patients regarding the risk of ovarian cancer. Transvaginal ultrasonography remains the modality of choice in the evaluation of suspicious characteristics. The combined analysis of ultrasound morphological parameters with Doppler study, serum carcinona antigen 125 and investigation of a symptom index may improve diagnosis. Surgical approach should be considered whenever there are suspicious images, rapid growth of cysts, changes in the appearance compared to the initial evaluation or when the patient has symptoms. Future studies on genetic and molecular mechanisms may help explain the pathophysiology of ovarian cancer, improving early diagnosis and treatment.

Resumo Em virtude da ampla utilização da ultrassonografia pélvica e transvaginal na avaliação ginecológica de rotina, o achado incidental de massas anexiais tem ocasionado discussões sobre a conduta em pacientes assintomáticas frente ao risco de desenvolvimento do câncer de ovário. A ultrassonografia transvaginal continua a ser a modalidade de primeira escolha na avaliação de características suspeitas. A análise conjunta de parâmetros morfológicos ultrassonográficos com o estudo Doppler, a pesquisa de CA-125 e a investigação de índice de sintomas pode incrementar as taxas de diagnóstico. Abordagem cirúrgica deve ser considerada sempre que houver alterações em exames de imagem, quando houver crescimento rápido do cisto, mudanças em seu aspecto em relação à avaliação inicial ou quando a paciente apresentar sintomatologia. Uma compreensão melhor de mecanismos genéticos e moleculares pode auxiliar na elucidação da fisiopatologia do câncer ovariano, aprimorando seu diagnóstico e tratamento precoces.

Comparison between baseline and contrast-enhanced ultrasound in characterization of adnexal masses / 中华超声影像学杂志

ObjectiveTo assess the diagnostic performance of contrast-enhanced ultrasound(CEUS)in characterization of adnexal masses in comparison with baseline ultrasound.MethodsOne hundred and thirty-seven masses were examined by CEUS and baseline ultrasound.Two independent investigators reviewed the images before and after contrast agent administration.The diagnostic performances were evaluated using receiver operating characteristic (ROC) analysis and the interobserver agreement was analyzed.ResultsAfter review of CEUS,ROC analysis revealed significant improvement in differentiating between malignant and benign pelvic masses that the areas under the ROC curve were 0.731 and 0.738 at baseline ultrasound versus 0.891 and 0.903 at CEUS ( P ＜0.01 ).The accuracy for both investigators also improved significantly after reviewing CEUS.A better interobserver agreement was achieved after reviewing of CEUS (g =0.681 at baseline ultrasound versus κ =0.893 at CEUS) and a better result of specific diagnosis was obtained (73.2％ and 74.2％ at baseline ultrasound versus 90.7％ and 91.2％ at CEUS)(all P ＜ 0.01 ).Conclusions Real-time CEUS improves the diagnostic performance in adnexal masses for discrimination between malignancy and benignity and improves the capability in specific diagnosis compared with baseline ultrasound.

Value of three-dimensional contrast-enhanced ultrasonography in diagnosis of small adnexal masses: a preliminary study / 中华超声影像学杂志

Objective To evaluate the value of three-dimensional contrast-enhanced ultrasonography (3D-CEUS) in diagnosis of small adnexal masses.Methods Forty-three patients with 47 adnexal masses were examined by both two-dimensional contrast-enhanced ultrasound (2D-CEUS) and 3D-CEUS.Sonographic features of adnexal masses with 3D-CEUS were analyzed and compared with 2D-CEUS.All patients with adnexal masses were proved by operational pathology and long-term follow-up results.Results Enhancement from the periphery to the parenchyma, septa or papillae was shown by 2D-CEUS among 40 benign adnexal masses, and multicenter enhancement from parenchyma to the periphery among 7 malignant ones.There were significant differences in blood vessels of envelope and septa, and the enhancement of parenchyma between benign and malignant adnexal masses by 3D-CEUS (P ＜0.05).Straight and sparse blood vessels were seen inside benign solid masses.Enhancement was observed in the wall of cystic masses,but not in intracapsular structures.Dense and distorted vascularity was found inside malignant adnexal masses forming a ball in the parenchyma, which was significantly enhanced.Thick vasa vasorum was also visible in 6 out of 7 malignant ones.Conclusions 3D-CEUS has an advantage in displaying complex spatial vascular structures,and might be a new tool to study real vascular structures in small adnexal masses.

Torção ovariana / Ovarian torsion

Torção ovariana é definida como a rotação parcial ou total do pedículo vascular ovarianoque promove estase circulatória, inicialmente venosa, e que se torna arterial com aprogressão da torção e do edema resultante. Sua manifestação clínica é inespecífica eassemelha-se às do abdômen agudo, o que pode levar à demora em sua identificação.A realização tardia do diagnóstico pode ocasionar a perda da tuba uterina, do ovário,ou de ambos com consequente infertilidade. O tratamento é cirúrgico.

Ovarian torsion is defined as a partial or complete rotation of the ovarian vascularpedicle promoting circulatory stasis that is initially venous and becomes arterial with theprogression of twisting and resultant edema. The nonspecific symptoms similar to acuteabdomen may lead to delay in its identification. Delayed diagnosis may lead to the loss ofa fallopian tube, ovary, or both, with consequent infertility. The treatment is surgical.

Tumor borderline do ovário localizado no canal inguinal: relato de caso / A borderline ovarian tumor in inguinal canal: case report

Os sintomas do tumor ovariano são inespecíficos e uma forma rara de apresentação é como conteúdo de uma hérnia inguinal. Relatamos o caso de uma paciente de 82 anos, com diagnóstico de câncer de mama e lesão anexial hipoecoica à ecografia. A mesma foi submetida à cirurgia conservadora da mama e à laparotomia, com achado de lesão ovariana sólido-cística no interior do canal inguinal à direita. A análise por congelação foi negativa para malignidade, e o exame anatomopatológico mostrou tratar-se de tumor ovariano borderline.

The symptoms of ovarian tumor are not specific and a rare presentation of the tumor is as the content of an inguinal hernia. We reported a case of an 82-year-old woman, diagnosed with breast cancer and with a concomitant hypoecoic adnexal mass at the ecographic exam. The patient was treated with conservative breast surgery and laparotomy. A cystic-solid ovarian lesion was found inside the right inguinal canal. Frozen-section examination was negative for malignancy, and the anatomopathological analysis revealed a borderline ovarian tumor.

Magnetic resonance imaging findings in adnexial torsion / Achados da ressonância magnética na torção anexial

Adnexial torsion is an unusual event, but a major cause of abdominal pain in women. It is often associated with ovarian tumor or cyst, but can occur in normal ovaries, especially in children. The twisting of adnexial structures may involve the ovary or tube, but frequently affects both. In most cases, it is unilateral, with slight predilection for the right side. In imaging findings, increased ovarian volume and adnexial masses are observed, with reduced or absent vascularization. In cases of undiagnosed or untreated complete twist, hemorrhagic necrosis may occur leading to complications; in that, peritonitis is the most frequent. Early diagnosis helps preventing irreversible damage with conservative treatment, thereby saving the ovary. Limitations in performing physical examination, possible inconclusive results in ultrasound and exposure to radiation in computed tomography makes magnetic resonance imaging a valuable tool in emergency assessment of gynecological diseases. The objective of this study was to report two confirmed cases of adnexial twist, emphasizing the contribution of magnetic resonance imaging in the diagnosis of this condition.

A torção anexial é um evento incomum, porém constitui importante causa de dor abdominal em mulheres. Está frequentemente associada a tumor ou cisto ovariano, mas pode ocorrer em ovários normais, principalmente em crianças. A torção de estruturas anexiais pode envolver o ovário ou a tuba, mas geralmente acomete ambos. Na maioria dos casos, é unilateral, com discreta predileção pelo lado direito. Como achados de imagem, observam-se massas ovarianas e aumento do volume ovariano, com redução ou ausência de sua vascularização. Se a torção for completa e não diagnosticada ou tratada, pode ocorrer necrose hemorrágica, evoluindo com complicações, sendo a peritonite a mais frequente. O diagnóstico precoce ajuda a prevenir danos que são irreversíveis com tratamento conservador, poupando-se o ovário. A limitação do exame físico, a possibilidade de resultados inconclusivos pela ultrassonografia e a exposição à radiação pela tomografia computadorizada fazem da ressonância magnética um complemento valioso na avaliação de emergência das doenças ginecológicas. O objetivo deste trabalho foi relatar dois casos confirmados de torção anexial, enfatizando a contribuição da ressonância magnética no diagnóstico dessa entidade.
