Brain MRI at one month of age. Axial T2-weighted MR image obtained at a ganglionic (a) and supraganglionic (b) level shows an increased signal intensity in the lentiform nuclei and ventrolateral thalami, in the periventricular white matter and within the subcortical U-fibers. Furthermore, the images show an enlargement of the lateral ventricles with irregular margins, fluid collection in the fronto-parietal area and a widening of the Silvian fissure
