Sagittal T1 MRI without contrast of the brain (above left) shows a large, isointense, heterogenous but primarily solid mass arising in the region of the pineal gland. On axial T2 MRI without contrast (above right) the mass is also isointense but has some cysts within it. Axial DWI MRI (below left) shows diffusion restriction in the mass while axial T1 MRI with contrast (below right) shows heterogenous enhancement of the mass.
