(a) and (b) Periventricular echogenic halo similar to that described for periventricular leukomalacia, mild ventriculomegaly, irregular choroid plexus; (c) a more severe case; echogenicities within the cortex are associated with an excessive size of the subarachnoid space suggesting microencephaly.
