Understanding Patchy Disappearance in Multiple Sclerosis (MS)

In multiple sclerosis (MS), the patchy disappearance and subsequent reappearance of T2 hyperintense lesions on magnetic resonance imaging (MRI) scans is frequently observed and clinically correlates with relapses and remission cycles, respectively.

This phenomenon is commonly referred to as the "Dawson's fingers" appearance due to its characteristic resemblance to the branching, irregular, linear-shaped pattern of affected white matter.
