WebFollow-up brain MRI revealed less prominent FLAIR high signal intensity, which implied improved PRES (Fig. 1E and F). Howev-er, the MRI findings of NIID were aggravated, and lesions were more prominent in the bilateral frontotemporal lobes (Fig. 1G and H). At discharge, the patient was alert, and her cognitive im-pairment and apraxia persisted [4].
