FIG 6. MR images of a relatively small astroblastoma in a 30-year-old male patient (patient 1).
A, Axial T2-weighted image (3466/84/1) shows the solid component of this left frontal lesion has the characteristic bubbly appearance of an astroblastoma (arrow), but a moderate amount of peritumoral T2 hyperintensity associated with the lesion (arrowheads) is present. Furthermore, the cystic component is absent.
B, Axial postcontrast T1-weighted image (550/8) shows the typically intense heterogeneous enhancement of the solid component. The overall imaging characteristics were nonspecific; histologic analysis confirmed the diagnosis of a well-differentiated astroblastoma.
