title: Demonstration of fourth ventricular choroid plexus on neonatal cranial ultrasonography.
abstract: The choroid plexus of the fourth ventricle can be identified on neonatal cranial US via the mastoid fontanelle, particularly when transducers of high frequency are used. Its presence as a normal, echogenic structure might not be appreciated by all sonographers. It should not be mistaken for vermian hemorrhage or clotted blood within the fourth ventricle or cisterna magna.
