FIG 1. Preterm infant of 26 weeks' (+3 days) gestation (case 6) at age 3 weeks.
A, T2-weighted (3500/208) FSE MR sequence shows the anterior cap within the periventricular white matter as high signal intensity (arrow) with a medial low signal component. There are abnormal low signal intensities within the globus pallidus and thalamus.
B, T2-weighted (3500/32/950) IR FSE sequence shows the anterior cap within the periventricular white matter as an area of low signal intensity (arrow) with a high-signal medial component. There are abnormal high signal intensities within the globus pallidus, putamen, and thalamus. The posterior limb of the internal capsule is seen as very low signal intensity.
