MRI

Brain MRI is helpful in the diagnosis of gliomatosis cerebri. On brain MRI, gliomatosis cerebri is characterized by:

MRI component	Findings
T1	Iso to hypointense to grey matter
T2	Hyperintense to grey matter
T1C+	No or minimal enhancement
DWI	No restriction
MR spectroscopy	E​levated choline/creatine and choline/NAA ratios Marked elevation of myo-inositol
MR perfusion	​Low/normal rCBV Correlates with no vascular hyperplasia
