Figure 1: Axial T1-weighted (a) shows a hypointense tumor predominantly in the midline with a cystic component situated anteriorly and to the right abutting the brainstem. Axial (b) and sagittal (c) T2-weighted images demonstrate the poor demarcation of the tumor from the brainstem. Post contrast axial (d), coronal (e) and sagittal (f) T1-weighted images show the heterogeneous nature of the tumor with enhancement of the solid component and the cyst wall
