WEB Dawson's Fingers: A Radiographic Feature of Demyelinating Diseases
What are WEB Dawson's Fingers?
WEB Dawson's fingers are a radiographic feature of demyelinating plaques distributed periventricularly, meaning they appear around the ventricles in the brain.
Association with Multiple Sclerosis
While WEB Dawson's fingers can occur in other demyelinating diseases, they are most commonly associated with multiple sclerosis (MS), an autoimmune disorder that affects the central nervous system.
In MS, WEB Dawson's fingers are typically seen in the early stages of the disease and are characterized by their ovoid shape and perpendicular orientation to the ventricles.
Clinical Significance
The presence of WEB Dawson's fingers on brain scans is considered an important diagnostic indicator for MS. However, it is important to note that not all people with MS will exhibit this finding.
