case_images: However, some mistakes were evident, such as the separation of hexagons (Fig. 1a). Additionally, while copying a cube, a mistake led to the distortion of the shape with depth (Fig. 1b).

case_images: The brain magnetic resonance imaging (MRI) showed a high signal intensity in the left hippocampus on diffusion-weighted images (Fig. 2a, b), a low apparent diffusion coefficient range, and a slightly high signal intensity on fluid-attenuated inversion recovery (FLAIR) images. Magnetic resonance angiography (MRA) showed fetal-type variations in the posterior communicating arteries on both sides and poor visualization of the left posterior cerebral artery after P2 (Fig. 2c). Five days later, a follow-up MRI revealed improvement in the left posterior cerebral artery (Fig. 2d).
