Overt enlargement of the lateral ventricles due to increased intracranial pressure is called what?

Explanation:
Hydrocephalus is the term for enlargement of the brain’s ventricles due to accumulation of cerebrospinal fluid, which raises intracranial pressure. On ultrasound, this presents as ventriculomegaly, often evaluated by measuring the lateral ventricle atrial width (a value around 10 mm or more in the fetus or neonate suggests dilatation). The distinction matters because hydrocephalus reflects CSF buildup, whereas the other terms refer to different issues: frontal bossing is a skull contour finding from certain conditions, and oligohydramnios/polyhydramnios describe abnormal amniotic fluid volumes, not ventricular size.
