Diagnosis of fetal cortical abnormalities by new reference charts for assessment of sylvian fissure biometry.

Objective: To develop novel fetal reference ranges for the characterization of the normal appearance of the Sylvian fissures (SF) along gestation and to apply them to fetuses with cortical abnormalities affecting the SF.

Methods: In this cross-sectional study, we used three-dimensional sonographic multiplanar reformatting (3D-MPR) to examine the fetal SF. Normal development was assessed in the second and third trimesters.

A New Insight on Exophytic Serous Borderline Adnexal Tumors: Specific Sonographic Features.

Objectives: To characterize and compare the sonographic features of exophytic serous borderline ovarian tumors (ESBOT) with those of high-grade serous carcinoma of the ovary (HGSC).

Methods: Seven patients with histological diagnosis of ESBOT diagnosed between 2011 and 2019 and 10 consecutive cases of HGSC detected during 2019, both depicting an exophytic growth pattern, were identified retrospectively. The sonographic imaging of the masses was reassessed and characterized according to the International Ovarian Tumor Analysis terms.

Unique Imaging Features Enabling the Prenatal Diagnosis of Developmental Venous Anomalies: A Persistent Echogenic Brain Lesion Drained by a Collecting Vein in Contrast with Normal Brain Parenchyma on MRI.

Objective: To describe the prenatal imaging features enabling diagnosis of developmental venous anomalies (DVA).

Methods: Four fetuses with unexplained persistent echogenic parenchymal brain lesions were studied. The evaluation included dedicated neurosonography, fetal MRI, serology for intrauterine infection, screening for coagulation abnormalities, and chromosomal microarray.

The nuchal translucency examination leading to early diagnosis of structural fetal anomalies.

Objective: To evaluate the ability to diagnose structural fetal anomalies during or soon after an extended nuchal translucency (NT) examination.

Methods: The study population included all women who had a routine NT examination in the ultrasound division of one of three centers. Also included in the study were women referred to these centers following an abnormal NT examination.

Sonographic evaluation of the superior sinus sagittalis.

Objective: The aim of this study was to characterize the normal ultrasonographic growth of the fetal superior sinus sagittalis (SSS) throughout gestation.

Patients And Methods: In a prospective cross-sectional study, measurements of the fetal sinus sagittalis were obtained in patients undergoing elective fetal anatomical surveys or fetal growth scan at between 16.6 and 34.

Doppler studies of the ovarian venous blood flow in the diagnosis of adnexal torsion.

Purpose: To evaluate the role of ovarian Doppler studies in diagnosing adnexal torsion.

Methods: We included in that study all patients who had an adnexal mass with clinical symptoms of intermittent lower abdominal pain and were hospitalized for at least 48 hours of observation. Our protocol included: measurements of the size of the adnexal mass, presence or absence of ovarian edema, presence or absence of adnexal vascularity, presence or absence of ovarian artery flow, presence or absence of ovarian venous flow, pattern of ovarian venous flow.

Fetal cardiac scanning performed immediately following an abnormal nuchal translucency examination.

Objective: To study the implications of early fetal cardiac scanning immediately following an abnormal nuchal translucency (NT) examination.

Methods: Fetal cardiac scanning was performed immediately after an increased NT was observed. Scans were performed transvaginally at 11 to 14 weeks.
