Figure 1:
- FLAIR axial image (A) through midbrain – No abnormal signal intensity in the midbrain
- T2_3D axial image (B) through midbrain – subtle hyperintense signal in the left paramedian midbrain
- this lesion shows diffusion restriction on DWI (horizontal arrow on C)
- ADC map (vertical arrow on D) which is classic of acute infarct
Figure 2: Acute infarcts in the left cerebellar hemisphere on a lower section through cerebellum seen as areas of diffusion restriction on DWI.
