ABSTRACT: Background: Early identification of fetuses with abnormal fetal growth and extreme birth weights is essential, as these conditions are associated with increased perinatal morbidity and mortality. Objective: To evaluate the accuracy of estimated fetal weight (EFW) obtained by ultrasonography compared with birth weight (BW) in fetuses with EFW 2 = 0.85). Conclusion: Ultrasonographic estimation of fetal weight showed good agreement with birth weight in fetuses with extreme estimated fetal weights, supporting its use in clinical decision-making. Findings regarding fetuses with EFW ≥ 4000 g should be interpreted cautiously due to the limited number of cases.
