A 36-year-old, healthy male was accidentally sprayed over the face and trunk with the liquid form of DMAB (Figure 2).
MRIs of the patient. (A) Symmetric increase in signal intensity at bilateral cerebellar periventricular area on T2WI (9 February 2004). (B) Previous cerebellar dantate nuclei region hyperintensity on T2WI has subsided (17 March 2004).

Brain magnetic resonance imaging (MRI) on the eighth day showed a symmetric increase in signal intensity on FLAIR (fluid-attenuated inversion recovery), T2WI (T2-weighted intensity), and DWI (diffusion-weighted images), but low signal intensity on T1WI without postcontrast enhancement at bilateral cerebellar periventricular areas (Figure 3A). A brain MRI on the 37th day after poisoning showed that the previous lesions in the cerebellar dentate nuclei region had subsided (Figure 3B).
