FIG 2. The classic MR imaging appearance of an astroblastoma in a 3-year-old female patient (patient 5).
A and B, Axial T2-weighted images [2500/90/1 (TR/TE/excitations)] depict a large, well-circumscribed, heterogeneous supratentorial mass with peripheral cystic changes (arrows). Note that the solid component of the mass has a heterogeneous bubbly appearance in its center.
C and D, Axial postcontrast T1-weighted images (500/20/1) show rim enhancement of the cystic component (arrows) and heterogeneous enhancement of the solid component. In this case, the tumor was malignant.
