Cerebral edema in neonates

Cerebral edema remains one of the commonest problems encountered whilst doing sonographic imaging of the neonatal brain. It has been graded into mild, moderate and severe depending on the degree of effacement or compression of the ventricular system- the lateral and 3rd veintricles mainly, and also loss of the sulcal pattern of the baby's brain.
These ultrasound images of severe cerebral edema show the typical appearance with the lateral and 3rd ventricles virtually compressed out of visibility by the edematous neonatal cerebral tissue (the sulcal pattern is however, still preserved and is visible):
