Two different patients with molecular diagnosis of ET. (a & b) A 10-year-old female with axial T2 weighted (a) and axial post contrast T1 weighted (b) images demonstrating a large mass centered in the left deep nuclei with a prominent cystic component, and moderate enhancement of the solid component. The tumor subclass was CNS_NB_FOXR2. Please note the similarities with high grade glioma and ependymoma illustrated in fig 5. (c & d) A 5-year-old female with axial T2 weighted (c) and sagittal post contrast T1 weighted (d) images demonstrating a large solid mass centered in the right lateral ventricle with minimal to no enhancement. The tumor subclass was ETMR. Of note, both these tumors demonstrated diffusion restriction (not shown).
