A 52-year-old patient with cyclosporine toxicity. Eleven days before the seizure, a pretransplant surveillance 3T MR imaging with FLAIR (A), SWI (B), and postcontrast T1WI (C) had normal findings. At presentation for seizure with mild PRES, 1.5T FLAIR (D) showed vasogenic edema, with a new punctate MH on SWI (E) and cortical and leptomeningeal contrast enhancement on postcontrast T1WI (F). After the episode of PRES clinically resolved, a 5-month follow-up MR image at 3T showed no edema on FLAIR (G), while the MH remained on SWI (H). The MH also persisted on a 1.5T SWI at 9 months (I).
