Abstract
We report a patient with NF1, who was followed up because of an optic glioma and one enhancing lesion presumed to be a pilocytic astrocytoma. T1- and T2-weighted MR images showed also a hyperintense periventricular lesion with no enhancement and no mass effect, of an unsuspected nature. Three years later a glioblastoma multiforme developed at the site of this preceding lesion.
