Abstract
A 66‐year‐old man developed a focal status epilepticus and left hemiparesis 4 days after an orthotopic liver transplantation and administration of FK 506. The magnetic resonance image revealed areas of increased signal on diffusion‐weighted imaging (DWI) equally distributed to all vascular territories, most of which resolved completely within 2 weeks after discontinuation of FK 506. We conclude that DWI cannot reliably distinguish between reversible and irreversible lesions and that the presence of hyperintense lesions on DWI is not a definitive predictor of poor prognosis in reversible leukoencephalopathy patients.
