Figure 8: (a) Diffusion weighted imaging (DWI) shows a focal small hyperintensity in left anterior thalamic region which on T2W: (b) also appears hyperintense suggestive of acute infarct in left thalamic region. There is T2W hypointense lesion in left perimesencephalic cistern (c) which on TOF MRA confirmed to be aneurysm (d). MRI done after embolization of the aneurysm showed no new infarct in PCA territory in DWI (e and f) and T2W (g and h); old infarct in thalamic region is seen as before (e and g)
