Brain MRI abnormalities associated with amyotrophic lateral sclerosis: A case illustration

Abstract

Amyotrophic lateral sclerosis is a progressive neurodegenerative pathology. It involves both upper and lower motor neurons, leading to their degeneration. Lower motor neurons can be detected with an electromyogram, but the detection of upper motor neuron dysfunction may be more accurate using MRI. We present the case of a 64-year-old woman with amyotrophic lateral sclerosis, presenting the motor band sign and the bright tongue sign on MRI.
