Multiplanar multisequence MRI shows the pons is swollen with a T1 hypointense / T2 hyperintense mass suggestive of intrinsic pontine glioma. Post-contrast T1 images show minimal focal enhancement is present. Note absence of hydrocephalus despite size of mass.
DWI and spectroscopy confirms the malignant nature of the disease.
MR spectroscopy demonstrates increased Cho and decreased NAA.
