Henry Hun's case of lateral medullary syndrome (1)

Henry Hun's case of lateral medullary syndrome (1897), 4 years before the pathology from Wallenberg's case was published. Represents a section through the medulla oblongata in a plane corresponding to the upper vagus or glossopharyngeal roots, and 2 or 3 mm candad to the plane of junction of the pons and medulla. The focus of softening is shown at X, and areas of degeneration are shown surrounding and within both olivary bodies. The section is not strictly transverse, the right side being slightly cephalad to the left. The anterior pyramids became detached from this section and are not represented. (Source: Hun H.
