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

Download

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. Analgesia, thermic anaesthesia, and ataxia, resulting from foci of softening in the medulla oblongata and cerebellum, due to occlusion of the left inferior posterior cerebellar artery. A study of the course of the sensory and co-ordinating tracts in the medulla oblongata. N Y Med J 1897;65:513-9. Edited by Dr. Douglas J Lanska.)
