Wallenberg Syndrome MRI with arrow
Diffusion-weighted MRI of an infart in the left dorsolateral medulla, consistent with a clinical picture of Wallenberg syndrome. The infarct in this image would be in approximately the same location as the one shown in the pathology image. In the MRI, dorsal is toward the bottom of the image, whereas in the pathology image, dorsal is toward the top. Also, in MRI imaging, anatomic left is on the right of the image, whereas in photographs of pathology specimens, it is customary for anatomic left to be on the left. The unnecessarily large green arrow points to the area of diffusion restriction (bright area), which in this case indicates an infarct.
