CEREBRAL MALFORMATIONS VENTRICULOMEGALY AND HYDROCEPHALUS
Ventriculomegaly has been cited as the most common cranial abnormality.
— Suspicion of ventricular dilatation occurs when the atrial diameter measures greater than 10 mm.
— The lateral ventricle that will be readily seen on sonography is most often the ventricle farthest away from the transducer.
— The sonographic finding of the “dangling choroid” sign describes the echogenic choroid plexus, hanging limp and surrounded by CSF, within the dilated lateral ventricle.
