Purpose The aim of this study was to evaluate whether corpus callosum length (CCL), corpus callosum‐fastigium length (CCFL) and the angle between CCL‐CCFL (CCFA) were altered in growth‐restricted fetuses. Methods This prospective case–control study was conducted in a tertiary center. A total of 80 singleton fetuses were included in the study, classified as 36 late‐onset growth‐restricted fetuses and 44 adequate‐for‐gestational‐age fetuses. All biometric measurements and Doppler assessments of umbilical artery, middle cerebral artery, and ductus venosus were performed via the trans‐abdominal route. CCL, CCLF, and CCFA were assessed via the trans‐vaginal route. Results Late‐onset growth‐restricted fetuses showed significantly reduced CCL and CCFL. There was no statistically significant differences in terms of CCFA. Moderate‐high correlations between CCL and biparietal diameter, head circumference, abdominal circumference, FL and gestational age were detected ( r : 0.482 p : 0.000; r : 0.537 p : 0.000; r : 0.488 p : 0.000; r : 0.519 p : 0.000; and r : 0.472 p : 0.000, respectively). Conclusion This study adds to the literature that CCFA has not changed despite the decrease in CCL and CCFL in late‐onset fetal growth restriction that might be a result of the redistribution of cerebral blood flow. To clarify the prognostic implications of these results in terms of neural and cognitive functions in postnatal life, there is a need for larger prospective studies.
