Gadolinium chelates are extensively used in MRI studies. Neurotoxicity due to gadolinium chelates is minimal and uncommon. A 57-year-old woman in renal failure developed a subacute encephalopathy after inadvertent repetitive gadolinium contrast administration. An unusual MRI appearance with CSF hyperintensity due to gadolinium diffusion into the CSF is also shown.
