Fig 1. Patient 1 is a 39-year-old man with baseline blood pressure 122/61 mm Hg who had severe pneumonia with bronchial obstruction. Bronchial lavage grew Staphylococcus aureus and blood culture grew coagulase-negative staphylococci. Neurotoxicity developed 13 days after positive cultures with severe headache followed by a seizure with blood pressure at toxicity 118/70 mm Hg.
A–B, Brain MR imaging (FLAIR sequence) demonstrates moderate signal intensity abnormality from vasogenic edema in the occipital lobes bilaterally (open arrows) typical of the PRES pattern with full extension to the ventricular surface and moderate local cortical mass effect judged grade 3. Follow up imaging was not obtained, but the patient’s symptoms resolved completely.
