“…The transverse diameters of the atria of the lateral ventricles were measured in the axial plane superior to the level of the thalami. Unilateral ventriculomegaly was defined as an atrial diameter greater than 1.0 cm or 1.0 cm with a dangling choroid plexus (the finding of a choroid plexus not filling the lateral ventricle and with a subjectively increased angle between the long axis of the choroid plexus and the linear midline echo of the fetal brain) 6 found on only 1 side of the fetal head. Satisfactory images of both ventricles were required to diagnose UVM.…”

The objective of this study was to determine the frequency of prenatally diagnosed unilateral cerebral ventriculomegaly and also to assess neonatal outcome in infants with this prenatal diagnosis. A computerized ultrasonography database identified fetuses with isolated and nonisolated unilateral cerebral ventriculomegaly from October 1994 to June 1999. The Denver II Developmental Screening Test was used to assess developmental skills. Unilateral cerebral ventriculomegaly was diagnosed in 15 of 21,172 (1 per 1411) pregnancies. The width of the enlarged lateral ventricle ranged from 1.0 to 1.9 cm. In 10 (67%) of 15 cases unilateral cerebral ventriculomegaly was an isolated finding. Eight of the 14 infants who were born at 36 weeks' gestation or later had postnatal cranial imaging, and ventricular asymmetry was confirmed in 5 (63%). One infant with an arachnoid cyst and cerebral palsy died at 2 years of age. The remaining 11 infants in whom developmental milestones were assessed had age-appropriate skills. Unilateral fetal ventriculomegaly is usually an isolated finding and when isolated has little measurable effect on developmental outcome. Key words: neonatal outcome assessment; prenatal ultrasonographic diagnosis; unilateral cerebral ventriculomegaly.

“…3 Suggested diagnostic criteria for fetal ventriculomegaly include an atrial diameter greater than 1.0 cm, 4 an abnormal ratio of the lateral ventricle to the hemispheric width, 5 and the "dangling choroid sign." 6 Most often ventriculomegaly is bilateral. Occasionally, asymmetry of the lateral ventricles is noted, with enlargement of only 1 side.…”

Nomograms of the fetal lateral ventricles were obtained by the transvaginal approach. Three hundred low‐risk women with no sonographically apparent fetal anomalies were scanned prospectively in a cross‐sectional study. Three measurements in the parasagittal plane, three in the midline coronal plane, and two in the posterior coronal plane were used to generate seven nomograms. Two additional nomograms reflecting two calculated ratios also were created. A mean regression line and the 5th and 95th confidence intervals were determined. We concluded that transvaginal sonography of the fetal brain generates images of both hemispheres of good enough resolution to allow several precise and reproducible measurements.

Purpose:To prospectively assess the frequency and cause of disagreements in diagnoses at ultrasonography (US) and magnetic resonance (MR) imaging for fetuses referred for ventriculomegaly (VM). Materials and Methods:One hundred ninety-five women, aged 18 -44 years, with 200 fetal referrals for VM, were recruited in a prospective IRB-approved, HIPAA-compliant study. Written informed consent was obtained. US scans were prospectively interpreted by three obstetric radiologists and MR examinations were read by one obstetric radiologist and three pediatric neuroradiologists. Final diagnosis was reached by consensus (198 US, 198 MR,. Gestational age, ventricular size, types of disagreements, and reasons for disagreements were recorded. Interreader agreement was assessed with statistics. Ventricular diameter, gestational age, and confidence scores were analyzed by using mixed-model analysis of variance, accounting for correlation within reader and fetus. Results:There was prospective agreement on 118 (60%) of 198 US and 104 (53%) of 198 MR readings. Consensus was more likely when the final diagnosis was isolated VM (83 of 104, 80% at US; 82 of 109, 75% at MR) than when the final diagnosis included other anomalies as well (14 of 63, 22% at US; seven of 68, 10% at MR; P Ͻ .001). There was disagreement on 19 (10%) of 196 and 31 (16%) of 196 fetuses about the presence of VM at US and MR, respectively, and on 29 (15%) of 198 and 39 (20%) of 198 fetuses regarding the presence of major findings at US and MR, respectively. Reasons for discrepancies in reporting major findings included errors of observation, lack of real-time US scanning, lack of neuroradiology experience, as well as modality differences in helping depict abnormalities. Conclusion:Of radiologists who read high-risk obstetric US and fetal MR images for VM, there is considerable variability in central nervous system diagnosis.
