RESUMO
OBJECTIVE: The purpose of this study was to describe a new reporting system called the Gynecologic Imaging Reporting and Data System (GI-RADS) for reporting findings in adnexal masses based on transvaginal sonography. METHODS: A total of 171 women (mean age, 39 years; range, 16-77 years) suspected of having an adnexal mass were evaluated by transvaginal sonography before treatment. Pattern recognition analysis and color Doppler blood flow location were used for determining the presumptive diagnosis. Then the GI-RADS was used, with the following classifications: GI-RADS 1, definitively benign; GI-RADS 2, very probably benign; GI-RADS 3, probably benign; GI-RADS 4, probably malignant; and GI-RADS 5, very probably malignant. Patients with GI-RADS 1 and 2 tumors were treated expectantly. All GI-RADS 3, 4, and 5 tumors were removed surgically, and a definitive histologic diagnosis was obtained. The GI-RADS classification was compared with final histologic diagnosis. RESULTS: A total of 187 masses were evaluated. The prevalence rate for malignant tumors was 13.4%. Overall GI-RADS classification rates were as follows: GI-RADS 1, 4 cases (2.1%); GI-RADS 2, 52 cases (27.8%); GI-RADS 3, 90 cases (48.1%); GI-RADS 4, 13 cases (7%); and GI-RADS 5, 28 cases (15%). The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy were 92%, 97%, 85%, 99%, and 96%, respectively. CONCLUSIONS: Our proposed reporting system showed good diagnostic performance. It is simple and could facilitate communication between sonographers/sonologists and clinicians.

Se revisa la importancia del ultrasonido bidimensional introital y transvaginal en el estudio de la uretra, vejiga y como apoyo diagnóstico en la incontinencia de orina de esfuerzo. Destacando además la importancia de éste en el control postoperatorio. Se trata de un examen de bajo costo, no invasivo, y sin contraindicaciones.

Se presenta el caso de un feto portador de un quiste ovárico de gran volumen, en una madre con diabetes gestacional. A las 29 y media semanas se punciona el quiste extrayéndose 500 cm3. El embarazo se interrumpe a las 33 y media semanas por la presencia de una Colestasia Intrahepática del Embarazo (CIE)
