Peripherally-enhancing lesion with central restricted diffusion in the right basal ganglia and internal capsule (red arrows), highly concerning for a pyogenic abscess. Close proximity to the ventricular margin increases the risk for ventriculitis.

Although this case is not the best example of an abscess rim, there is a thin T2 and SWI hypointense rim (red arrows) with a thin internal SWI hyperintense ring (yellow arrow).

Enhancement extending along the superior margin of the right lateral ventricle (red arrow), which raises concern for developing ventriculitis.
