  Fig. 1 Brain MRI and visual field examination of the patient. A: Initial brain diffusion-weighted MRI shows no acute ischemic lesion. B: The mean transit time is delayed in the right parieto-occipital lobe in perfusion-weighted MRI. C: Magnetic resonance angiography shows that there is no significant steno-occlusive lesion in the posterior cerebral artery. D: A left homonymous field defect is noted in the initial visual field examination (upper panel), and this is normalized after steroid therapy (lower panel). E: Follow-up MRI shows no ischemic lesions. MRI: magnetic resonance imaging.
