Images of a 40-year-old man exposed to 5-Bromo-2-nitropyridine. Magnetic resonance imaging 82 days after exposure showing abnormal signal intensity on (A) T1WI, (B) T2WI, (C) DWI, and (D) DWI/ADC in the bilateral cerebral hemispheres. T1WI, T1-weighted image; T2WI, T2-weighted image; DWI, diffusion-weighted imaging; DWI/ADC, diffusion-weighted imaging/apparent diffusion coefficient.

Brain magnetic resonance imaging (MRI) showed symmetric abnormal signals [hypointensities on T1-weighted image (T1-WI) and hyperintensities on T2-weighted image (T2WI) and diffusion-weighted image (DWI)] in both the basal ganglia, corona radiata region, centrum semiovale, and thalamus; thus, a diagnosis of delayed encephalopathy was considered (Figure 1).
