Cystic mass in the left cerebellar hemisphere with an avidly enhancing mural nodule (red arrow).

Axial FLAIR sequence demonstrates hyperintense signal within the solid component (red arrow) contrasted with serpiginous hypointense flow voids (yellow arrows). Minimal parenchymal edema is noted along the margins of the cystic component of the mass (blue arrow).

Relative facilitated diffusion (low DWI signal and high ADC signal, red arrows) is demonstrated in the solid portion of the mass relative to brain parenchyma.
