T2-weighted magnetic resonance imaging (MRI) at the level of the cervicomedullary junction showing an ill-defined area of increased signal posterior and lateral to the left, tracking caudally into the region of the vagal nuclei of the medulla, representative of demyelination.

A fiber-optic endoscopic evaluation of swallow study revealed severe pharyngeal dysphagia, prompting magnetic resonance imaging (MRI) of the patient's brain and spine that showed an ill-defined lesion in the posterior aspect of the medulla concerning for glioma versus a demyelinating process (Figure 1).
T2-weighted MRI at the cervicomedullary junction 5 months later, showing the lesion volume decreased by 92% and no longer exhibiting signal enhancement, suggesting a regression of demyelination.

MRI of the cervicomedullary junction 5 months after presentation showed the lesion volume decreased by 92% and no longer exhibited signal enhancement, suggesting a regression of demyelination (Figure 2).
