Diagnosis:

Hyperacute (less than 1 day) cerebral infarct.

Discussion:

Figure 1 & 2 Axial T2W scan of brain showing no abnormality.

Figure 3 & 4 Diffusion Weighed axail scan of brain showing abnormal signallesions at left temporo-occipital lobe.

Figure 5 & 6 ADC scan of brain showing low signal intensity in the corresponding sites.
