Findings

MR diffusion

There is evidence of a cortical/subcortical T2-shine through on diffusion consistent with leptomeningitis, or evidence of T2 shine through within brain parenchyma consistent with cerebritis/cerebellitis/rhombencephalitis.

There is evidence of a parenchymal abscess or intraventricular infected sequestra with positive fluid restriction (i.e. positive DWI and positive ADC).

There is evidence of an extraaxial empyema with T2 shine-through (positive DWI/negative ADC: both hyperintense).

There is evidence of an extraaxial empyema with adjacent bone osteomyelitis having positive fluid restriction (positive DWI/positive ADC: DWI hyperintense/ADC hypointense) in both areas.

There is evidence of secondary arterial ischemic event.

No other significant imaging findings are present.
