MRI findings for case 2.Multifocal areas of signal hyperintensity predominantly limited to the cortex of the posterior parietal and occipital lobes on FLAIR T2-weighted images, including punctate areas of abnormality in the deep, periventricular white matter of the right frontal lobe and of the cortex of the right medial parietal lobe. MRI done 1 month following discharge revealed punctate lesions in the frontal lobe, representing subacute to chronic ischemic changes, but resolution of the T2 hyperintense lesions in the posterior distribution.

MRI findings for case 3.(A) Extensive areas of FLAIR T2-weighted signal hyperintensity in the subcortical white matter and overlying gray matter of the posterior, frontal, and occipital lobes. MRI findings for case 3.(A) Extensive areas of FLAIR T2-weighted signal hyperintensity in the subcortical white matter and overlying gray matter of the posterior, frontal, and occipital lobes. Parenchymal hemorrhage was seen in the high parietal region predominantly on the patients's left. (B-C) Follow-up MRI scan 1 month and 15 months following discharge showed progressive evolution and resolution of the T2 signal hyperintensities with residual encephalomalacia in the left parietal region. These findings were consistent with reversible posterior leukoencephalopathy complicated by hemorrhage; there was no evidence of infarction. Jessica N. Henderson et al.
