Fig 1. MR imaging and DTI of a 15-year-old patient with diffuse pontine tumor.
A, Sagittal T1-weighted image. The pontine tumor is diffusely infiltrative. B, Axial T2-weighted image. The pons appears expanded and hyperintense with an area of focal necrosis. C, Axial ADC map. The tumor demonstrates elevated diffusion, and the necrosis is extremely hyperintense. D, Axial FA map. The tumor demonstrates diminished fractional anisotropy, and necrosis is hypointense.
