Fig 2. Patient 7 is a 68-year-old woman with necrotic pancreatitis, a pancreatic abscess, and baseline blood pressure of 141/67 mm Hg. Abscess grew mixed flora with coagulase-negative staphylococci and Acinetobacter baumannii and blood culture was positive for coagulase-negative staphylococci. Altered mental status with PRES developed 7 days after positive cultures with blood pressure at toxicity of 168/68 mm Hg.
A-B, Brain MR imaging (FLAIR sequence) demonstrates vasogenic edema in the occipital (open arrows) and parietal region (curved arrows) bilaterally typical of PRES with extension into the deep white matter but no extension to the ventricle surface judged grade 2.
C-D, Brain MR imaging (FLAIR sequence) obtained 1 month after initial imaging and toxicity demonstrates near complete resolution of the edema in the occipital (open arrows) and left parietal region (curved arrow) with complete resolution in the right parietal area (arrow).
