Hyperglycemic hemianopia: A case report

Figure 1  Visual field over the central 30 degrees showed a right homonymous hemianopia.

Figure 2  Magnetic resonance imaging showed low signal intensity in the apparent diffusion coefficient map. A: Magnetic resonance imaging of the brain demonstrating isointensity on T1 sequence; B: Susceptibility weighted imaging; C: Left occipital subcortical T2; D: Fluid-attenuated inversion recovery hypointensity (orange arrow); E: Restricted diffusion; and F: Low signal intensity of the ADC map.

Figure 3 Magnetic resonance angiography imaging of the brain showed a mild stenosis. A: Magnetic resonance angiography demonstrating mild stenosis of the right posterior cerebral artery (orange arrow); and B: Arterial spin labeling showing decreased perfusion of the lesion (arrowhead).
