FIG 5. In patients who had an adverse outcome (stroke or death), T2/DWI scores (P < .001) and ADC values (P < .02) were consistently higher than those of patients who recovered. Patient 4 had cortical DWI hyperintensity at presentation. The patient then recovered and was subsequently lost to follow-up. Patients 6 and 11 had cortical DWI hyperintensity with progression to stroke at follow-up. Patients 14, 15, and 18 had cortical DWI hyperintensity and died before follow-up. Patient 7 had foci of intracranial hemorrhage at presentation. Patients 12 and 22 had severe brain stem PRES.
