Gadolinium deposition. Gadolinium deposition. A 13-year-old boy was diagnosed with a pilocytic astrocytoma and treated with chemotherapy, but no radiation. A, the first available pregadolinium T1WI without any abnormality in the dentate. B, A follow-up examination performed 10 years later now demonstrates T1 hyperintensity on TIWI within the dentate nuclei (arrows). The patient had undergone 37 gadolinium-enhanced examinations at this time point. K.M. Bond et al. AJNR Am J Neuroradiol 2017;38:1467-1474 ©2017 by American Society of Neuroradiology
