Coronal T2 (A) and axial TI FLAIR (B), ADC (C), and T2 (D) MR images of a 21-day-old boy. Coronal T2 (A) and axial TI FLAIR (B), ADC (C), and T2 (D) MR images of a 21-day-old boy. Global severity score = 22 (third quartile) (E). There is diffuse bilateral WM cerebral edema (3 points) (A–D) and multiple acute bilateral symmetric hemorrhagic WM lesions (T1 bright and T2 dark): frontal (moderate punctate, 2 points, and severe linear, 3 points) (A, boxes), parietal (moderate punctate, 2 points) (D, circles), and temporal regions (moderate punctate, 2 points, not shown). There are no visible occipital WM lesions. R indicates right; L, left. K.L. Benninger et al. AJNR Am J Neuroradiol 2019;40:347-352 ©2019 by American Society of Neuroradiology
