(a & b) A 15 year-old-female with molecular diagnosis of pineoblastoma. Sagittal T1 weighted post contrast (a) and axial diffusion weighted (b) MRI images demonstrate a mass centered in the pineal region with diffuse heterogeneous enhancement, small cystic foci and diffusion restriction. (c & d) A 9-year-old female with molecular diagnosis of ATRT_MYC. Sagittal T1 weighted post contrast (c) and axial diffusion weighted (d) images demonstrate a similar mass centered in the pineal region with diffuse heterogeneous enhancement, small cystic foci and diffusion restriction. Note the similarities in imaging appearance between the two examples.
