Bilateral putaminal necrosis due to methanol abuse.

Symmetrical lesions in the basal ganglia are accepted as the characteristic radiological feature of methanol toxicity. A case of chronic deliberate repeated methanol ingestion is presented. The typical MRI findings of basal ganglia lesions on T1 and T2 weighted images, FLAIR, diffusion and T1-weighted post Gadolinium images are presented. To our knowledge, this is the first case in which late diffusion and post contrast MRI images, showing necrotic sequelae due to methanol ingestion, are reported.
