Left Atrial Myxoma Presenting as Lateral Medullary (Wallenberg’s) Syndrome

Figure 1

MRI of the brain with and without contrast showing focal restricted diffusion within the left posterolateral aspect of the medulla with associated focal heterogeneous T2 hyperintense signal, indicative of an evolving focal subacute cerebrovascular accident. Alternatively, this finding may represent an acute-subacute focus of demyelination in the proper clinical setting.
