Two different patients with a molecular diagnosis of ET. (A and B), A 10-year-old girl with axial T2-weighted (A) and axial postcontrast T1-weighted (B) images has 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 and D), A 5-year-old girl with axial T2-weighted (C) and sagittal postcontrast T1-weighted (D) images has a large solid mass centered in the right lateral ventricle with minimal-to-no enhancement. The tumor subclass was ETMR. Of note, both of these tumors demonstrated diffusion restriction (not shown).
