Ultrasonic measurements of the posterior cranial fossa structures in neonates and infants.
The structures in the posterior cranial fossa of neonates and infants were visualized ultrasonically via the anterior fontanelle. The diameters of the cerebellar vermis, pons, fourth ventricle and cisterna vermis were measured in the midsagittal plane in neonates (n = 76), 1-month-old infants (n = 61) and 3- to 6-month-old infants (n = 35). The normal values obtained will be useful for evaluation of morphological abnormalities in the posterior cranial fossa.
