Objectives Measuring the posterior horn of the lateral ventricle in the fetus during ultrasound scans may be challenging. We aimed to examine this measurement feasibility, in relation to gestational age. Methods A cross‐sectional study was conducted, including nonanomalous fetuses, in which both lateral ventricles measured less than 10 mm during anomaly scans. The measurements were performed according to the International Society of Ultrasound in Obstetrics and Gynecology guidelines. Success rate of measuring both ventricles was assessed at different gestational ages. Association between lateral ventricle width with contralateral ventricle width, gender, gestational age, and fetal head position were assessed. Results A total of 156 cases were recruited. The lateral ventricle distal to the probe was measured in all cases. In 10 cases proximal lateral ventricle could not be adequately measured (failed proximal ventricle measurement group). In 146 scans both ventricle measurements were available. All 10 cases of failed proximal ventricle measurement were in third trimester (30–38 weeks). Success rate of measurement of both ventricles was 100%, 96.2%, 71.4%, and 37.5% for gestational week 14–29, 30–32, 33–35, and 36–38, respectively (P
