Abstract:
Transfontanel cranial ultrasonography reliably delineates ventricular size and anatomy in small infants. In these children, it is an excellent primary imaging technique for evaluation of the many clinical problems related to ventricular dilatation. Sonography can be useful for: detecting ventriculomegaly, differentiating nonobstructive ventricular dilatation from obstructive enlargement (hydrocephalus), determining the cause of hydrocephalus; aiding in the temporary management of patients with hydrocephalus; and aiding in the management of patients with permanent ventricular shunts.
