MRI brain diffusion weighted imaging series (a) and T2 (b) demonstrating bilateral paramedian thalamic infarcts. CTA vessel study. (c) Axial-Maximum Intensity Projection (MIP); (d) axial-3D-MIP; and (e) reconstructed 3D image demonstrates an Artery of Percheron (arrow) arising from the right Posterior Cerebral Artery P1 segment.

A CT angiogram (CTA) demonstrated focal areas of basilar artery narrowing, an Artery of Percheron (AOP) arising from the right PCA (Figures 1(c), 1(d), and 1(e)) and no large vessel occlusions. MRI brain demonstrated bilateral paramedian thalamic infarcts (Figures 1(a) and 1(b)) extending into the midbrain on diffusion weighted imaging (DWI).
