FIG 1. Case 12: 13-year-old girl with systemic lupus erythematosus who presented with hypertension and status epilepticus. MR imaging was performed 5 days later.

A–C, FLAIR axial sections show extensive subcortical white matter edema bilaterally (arrows) with only minimal cortical involvement. Lesions are in the parietal, occipital, posterior frontal, and posterior temporal lobes and in the left corona radiata (asterisk). Additional T2 hyperintensity is seen in the white matter around the lentiform nuclei (arrowheads). Findings are consistent with typical changes of PRES, especially in the parietooccipital regions, and were considered moderate (severity index = 2) for the purposes of this study.

D and E, Follow-up MR study obtained 150 days after initial neurologic examination reveals complete resolution of lesions on FLAIR images.
