"Dawson's Fingers" is a condition affecting the brain of Multiple Sclerosis patients. The condition is the result of inflammation around long axis of medular veins. This results in a finger-like appearance of the lesions extending mainly off the ventricles within the brain.

This morphologic appearance is named after the Scottish pathologist James Walker Dawson [1], who first defined the condition in 1916.
