Methanol is a toxic substance with extremely devastating effects upon exposure. The case described suffered from such kind of poisoning. MRI brain demonstrated necrosis bilaterally in the Putamen areas which is a classic hallmark finding. Additional Diffusion weighted imaging showed abnormal signal bilaterally in the putamen areas along with Diffusion positive bilateral lesions (possibly infarctions) in both the frontal and occipital lobes that were not evident on MRI with or without contrast.
