ABSTRACT
OBJECTIVES: To evaluate the performance of a two-step strategy compared with the International Ovarian Tumor Analysis (IOTA) - Assessment of Different NEoplasias in the adneXa (ADNEX) model for preoperative classification of adnexal masses. METHODS: An ambispective diagnostic accuracy study based on ultrasound data collected at one university hospital between 2012 and 2018. Two ultrasonographers classified the adnexal masses using IOTA Simple Rules (first step). Not classifiable masses were evaluated using the IOTA ADNEX model (second step). Also, all masses were classified using the IOTA ADNEX model. The sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV), positive likelihood ratio (LR+) and negative likelihood ratio (LR-), and receiver operating characteristic (ROC) curve were estimated. A P value of <.05 was used to determine statistical significance. RESULTS: The study included 548 patients and 606 masses. Patients' median age was 41 years with an interquartile range between 32 and 51 years. In the first step, 89 (14%) masses were not classifiable. In the second step, 55 (61.8%) masses were classified as malignant. Furthermore, for the totality of 606 masses, the IOTA ADNEX model estimated the probability that 126 (20.8%) masses were malignant. The two-step strategy had a sensitivity, specificity, PPV, NPV, LR+, LR-, and ROC curve of 86.8%, 91.01%, 51.9%, 98.4%, 9.7, 0.1, and 0.889, respectively; compared to IOTA ADNEX model that had values of 91.8%, 87.16%, 44.4%, 99%, 7.1, 0.09, and 0.895, respectively. CONCLUSION: The two-step strategy shows a similar diagnostic performance when compared to the IOTA ADNEX model. The IOTA ADNEX model involves only one step and can be more practical, and thus would be recommended to use.

Objective: To report the case of a pregnant woman with ultrasound diagnosis of altered fetal tegumental system and postnatal diagnosis of Omenn syndrome. Case presentation: A 27-year-old patient who presented at 31 weeks of gestation with prenatal ultrasound evidence of a fetus with significant scalp edema, echogenic amniotic fluid and scaly abdominal skin, with ichtyosis variant impression on diagnostic ultrasound. The baby was born with congenital erythroderma complicated with skin infection, and later developed septic shock and died. The genetic and pathologic workup led to the conclusion of Omenn syndrome. Conclusion: Omenn syndrome must be considered as part of the differential diagnoses when prenatal ultrasound shows findings of altered tegument system. Studies are required to assess the accuracy of ultrasound for prenatal diagnosis of erythroderma.
Objetivo: reportar el caso de una gestante con diagnóstico ultrasonográfico de alteración del sistema tegumentario fetal y diagnóstico posnatal de síndrome de Omenn. Presentación de caso: se presenta el caso de paciente de 27 años con embarazo de 31 semanas, con exploración ultrasonográfica prenatal que evidencia feto con edema significativo del cuero cabelludo, líquido amniótico ecogénico y descamación de la piel abdominal, con aproximación diagnóstica ultrasonográfica de variante de ictiosis. El recién nacido presentó eritrodermia congénita complicada con infección de piel, con posterior choque séptico y muerte. El estudio genético y patológico concluye síndrome de Omenn. Conclusión: el síndrome de Omenn debe ser tomado en cuenta en los diagnósticos diferenciales cuando en la ultrasonografía prenatal existan hallazgos ultrasongráficos de una alteración del sistema tegumentario. Se requieren estudios que evalúen la exactitud del ultrasonido en el diagnóstico antenatal de las eritrodermias.
