case_images: An electromyography (EMG) revealed evidence of a widespread neuropathic process with diffuse denervation and re-innervation (see Table 1); furthermore, a magnetic resonance imaging (MRI) displayed fatty replacement of the tongue with a bright tongue sign (Figure 1), raising suspicion for amyotrophic lateral sclerosis (ALS).
