Abstract: An anatomical variation known as the artery of Percheron (AOP) has a single artery that emerges from the proximal posterior cerebral artery (PCA). It will result in an infarction in both the thalamus and the paramedian regions with or without the involvement of the midbrain. It is rare, occurring in roughly 4–12% of people. Due to its frequent misidentification, the frequency of bilateral thalamic infarction caused by AOP blockage is unknown. It accounts for approximately 4–18% of thalamic strokes and 0.1–2.0% of all ischemic strokes. We examine the various clinical signs and imaging findings associated with AOP stroke in this series. We report five cases of AOP stroke admitted in our hospital with varied symptoms like altered sensorium, hypersomnolence, reduced consciousness, and one patient with hallucinations. It poses a great diagnostic difficulty because of the varied clinical presentation.
