Brain magnetic resonance imaging (MRI) showed ischemic lesions confined to the right pre- and postcentral gyri and the medial frontal cortex on diffusion-weighted images (DWI) and fluid-attenuated inversion recovery (FLAIR) images (Fig. 1a). Hypoperfused regions were mainly observed in the right hemisphere, such as the pre- and postcentral gyri, superior and inferior parietal lobules, supramarginal gyrus, angular gyrus, superior, middle, and inferior temporal gyri, and superior and middle frontal gyri (Fig. 1b). After the recognition trials for the real objects with the left hand, the patient was asked to draw the tested objects to evaluate whether or not she could recognize the items; she was able to draw all test items (Fig. 1c).
