A large predominantly cystic mass lesion with some solid enhancing component is noted within the right cerebellar hemisphere causing effacement and compression of the fourth ventricle with resultant moderate dilatation of the proximal ventricular system. Mild surrounding vasogenic edema is noted.
No diffusion restriction on DWI/ADC sequences. No dropout signal on SWI sequence.
