FIG 2. Patient 2 was an 8-day-old neonate with a skull fracture after forceps delivery. Transverse images obtained at days 2, 4, and 8.

Top row, T2-weighted images acquired with a fast spin-echo technique (5000/96) show an area of hemorrhage with surrounding edema in the left frontal lobe (arrow). At 4 and 8 days, progressive development of the increased signal intensity in the left cerebral peduncle is seen (arrowhead).

Middle row, DW images obtained by using a spin-echo echo-planar imaging sequence (3000/106) show areas of increased signal intensity in the right frontal, right temporal, left frontal lobes, as well as in the left frontopontine tract (arrowhead). Also shown is the area of hemorrhage with surrounding edema in the left frontal lobe (arrow).

Bottom row, ADC maps confirm truly reduced diffusion in the left cerebral peduncle (arrowhead). Interestingly the diffusion changes in the left frontal lobe subcortical white matter become less apparent on days 4 and 8, consistent with ADC pseudonormalization.
