2022年7月12日 · When lesions form along these ventricles, they create finger-like shapes that can be seen on an MRI. These shapes are called Dawson’s fingers. The condition was named after Dr. James Dawson,...

2023年3月7日 · Dawson fingers are a radiographic feature of demyelination characterized by periventricular demyelinating plaques distributed along the axis of medullary veins, perpendicular to the body of the lateral ventricles and/or callosal junction. This is …

2019年5月20日 · People with multiple sclerosis (MS) often have a pattern of plaques, or lesions on the brain that doctors call Dawson's fingers. These are visible on brain scans and may be useful in diagnosing...

This morphologic appearance was named Dawson's fingers by Charles Lumsden, after the Scottish pathologist James Walker Dawson, [31] who first defined the condition in 1916.

2021年12月1日 · Dawson fingers. Typical findings for MS as seen in this case are: Ovoid lesions perpendicular to the ventricles (Dawson fingers). Enhancing lesion. Multiple lesions adjacent to the ventricles. Dawson fingers are typical for MS. They represent areas of demyelination along the small cerebral veins that run perpendicular to the ventricles.

2024年3月4日 · Turns out, “Dawson’s fingers” is a bit of a misnomer—they have nothing to do with your hands. Instead, they are vaguely finger-shaped scars on your brain (called lesions) that indicate MS....

2023年5月18日 · What Does It Mean by Dawson’s Fingers? Dawson's fingers appear to be elongated, with bright white shapes that extend at right angles from the brain ventricles on an MRI (magnetic resonance imaging). The severity of the condition influences the size of the lesions.

Dawson’s fingers, also known as periventricular lesions or Dawson’s fingers sign, are a characteristic radiological finding in magnetic resonance imaging (MRI) scans of the brain. The presence of Dawson’s fingers results from the demyelination process that occurs in …

Health Central, an online resource for patients with chronic or serious medical conditions, talked with Anjali Shah, M.D., director of the neurorehabilitation program in the UT Southwestern Clinical Center for Multiple Sclerosis, about an MS indicator called “Dawson’s fingers.”

Multiple Sclerosis (MS) is one of the most prevalent neurologic disorders in the world. James Walker Dawson examined, in considerable depth, the gross and histologic patterns of MS. Today, periventricular plaques that exhibit an appearance typical for demyelination are nicknamed "Dawson's Fingers." …
