Y. Miaux et al., HIGH-INTENSITY LESION ON T1-WEIGHTED MR-IMAGES IN NEUROFIBROMATOSIS TYPE-1 - A CASE OF PREMALIGNANT LESION, Acta neurochirurgica, 139(11), 1997, pp. 1085-1087
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 periventric
ular lesion with no enhancement and no mass effect, of an unsuspected
nature. Three years later a glioblastoma multiforme developed at the s
ite of this preceding lesion.
