Abstract: Objective To detect the normal values of fetal cerebellar vermis using transabdominal ultrasonography and assess its clinical significance in the diagnosis of vermal hypoplasia(agenesis). Methods A total of 111 fetuses were evaluated by transabdominal sonography between 20 and 40 weeks of gestation.The mid-sagittal antero-posterior(AP) and cranio-caudal(CC) vermian diameters were measured. A second group of 15 fetuses with cisterns magna were assessed and compared with the value of normal fetuses.0.05) and correlated linearly with gestational age ( AP = - 5.406 + 0. 761 GA, r = 0.97 ; CC = - 5.795 +fissure, second fissure and fastigium may help identify developmental anomalies. Conclusions Transabdominal ultrasonography is a valuable tool in the study of fetal vermis during the second half of pregnancy.
