Figure 2e. (a) Axial T1-weighted image shows that the tumor is iso- to hypointense. Arrows = hyperintense areas consistent with hemorrhage. (b) Axial T2-weighted image shows that the tumor is largely heterogeneous with hypointense areas representing calcifications (top arrow) and hyperintense areas consistent with necrosis (bottom arrow). (c) Axial FLAIR image shows that the tumor is moderately hyperintense with central areas of high signal intensity due to necrosis (arrows). (d, e) Coronal (d) and axial (e) gadolinium-enhanced T1-weighted images show moderate enhancement of the tumor with nonenhancing areas of necrosis (black arrows). White arrows = invasion of the overlying meninges and bone.
