Hyperintense on Diffusion-Weighted Images (DWI) and hypointense on Apparent Diffusion Co-efficient images (ADC) in keeping with acute infarction. Note : DWI iamges include B = 0, 500. 1000. Axial Time of Flight (TOF) MR angiogram showing a fetal origin of the left Posterior Cerebral Artery (PCA). At the level of the basilar tip, the origin of a tiny unpaired artery is noted which was presumed to be the occluded Artery of Percheron.Similar finding is demonstrated in the 3D rendering.
