We reported a rare case of cardioembolic stroke involving the territories of both the posterior cerebral artery (PCA) and the anterior choroidal artery. An 86-year-old man with atrial fibrillation was admitted to our hospital with consciousness disturbance and left hemiparesis. Diffusion-weighted imaging revealed high intensity lesions in the territories of the PCA and the anterior choroidal artery, leading us to make a diagnosis of cardioembolic stroke. Magnetic resonance angiography disclosed occlusion of the right internal carotid artery (ICA) and the right PCA. The P1 segment of the right PCA was absent, indicating that the right PCA had branched from the right ICA. Therefore, we believed that ICA occlusion caused the infarcts in the territories of both the PCA and the anterior choroidal artery. This is a rare stroke case involving the territories of both the PCA and the anterior choroidal artery.
