Dawson fingers are a radiographic feature depicting demyelinating plaques through the corpus callosum, arranged at right angles along medullary veins (callososeptal location). They are a relatively specific sign for multiple sclerosis (MS), which presents as T2 hyperintensities.

History and etymology

Dawson fingers are named after Scottish pathologist James Walker Dawson(1870-1927 ³) who described the phenomenon on histopathological specimens in an article in 1916 ², although the term "Dawson fingers" was brought forward by Charles Lumsden.
