Abscess. Right occipital mass showing marked diffusion restriction within the core on DWI and ADC maps (a and b, respectively) and a peripheral enhancing pattern on T1 post gadolinium (c). DWI helps to differentiate ring-enhancing lesions because restricted diffusion in the centre of the mass is characteristic of pyogenic abscesses. In this case, diffusion-based sequences also helped to identify ventriculitis (arrows)
