Figure 8a. Pilocytic astrocytoma with solid enhancement. (a) Sagittal T1-weighted image shows a well-circumscribed, hypointense cerebellar mass (m). (b) Axial T2-weighted image shows the hyperintense mass of the cerebellar vermis and right cerebellar hemisphere. (c) Contrast-enhanced sagittal T1-weighted image demonstrates homogeneous enhancement of the mass.
