Henry Hun's case of lateral medullary syndrome (8)

Henry Hun's case of lateral medullary syndrome (1897), 4 years before the pathology from Wallenberg's case was published. A section through the medulla oblongata at a level near the caudal end of the fourth ventricle. This shows the undegenerated tracts of Flechsig and Gowers and degenerations in the lateral portion of the formatio reticularis on the left side, in the descending root of the left fifth nerve, surrounding both olives, and to a lesser degree in the right anterior pyramid.

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.)
