Figure 13 (A-F).

A 24-day-old term neonate with low birth weight, CSF proven meningitis, and meconium-stained amniotic fluid showing prolonged severe hypoxic ischemic injury; mixed pattern involving deep grey matter and white matter. Axial T1WI at the level of basal ganglia (A) and lateral ventricles (B). Note the abnormal T1 hyperintensity of the basal ganglia and thalami (compare with Figure 1) and T1 hypointensity of cystic changes in the periventricular and subcortical white matter. Also note the false positive T1 hyperintensity of the posterior limb of internal capsule. Axial T2WI at the level of basal ganglia (C) and lateral ventricles (D). Note the abnormal T2 hypointensity of the basal ganglia and thalami (compare with Figure 1) and T2 hyperintensity at the level of posterior limb of internal capsule. Also note the T2 hyperintensity of cystic changes in the periventricular and subcortical white matter. (E, F) Axial FLAIR images at the level of basal ganglia and lateral ventricles. Note the cystic changes in the periventricular and subcortical white matter
