Child a few months old, ultrasound after birth without features.
At the current US - periventricular leukomalacia.
PS. Speaking of differentiation of enhancing periventricular echogenicity with leukomalacia - I' ve heard about the criteria of comparison to the echogenicity of the vascular plexus of the lateral ventricles, in case of leukomalacia echogenicity should be higher then echogenicity of vascular plexus ... But here we see the opposite.
