Dawson's finger

Postby sou » Wed May 13, 2009 3:57 pm

Hi all.

I was reviewing my older MRIs. I can now understand why my diagnosis was that straight forward. All my brain lesions are either at the edges of the ventricles or around the veins of the periphery of the brain. Pretty interesting finding since this is a very typical "Dawson's finger" image, with lesions being not circular but expanded around the axis of the vein.

How many of you have such a brain condition?

My neuro. mentioned that my MRI was a near perfect example of Dawson's fingers. Never really went on to elaborate.

I have dawsons fingers ...my most recent mri o 12/29/08 states

Extensive bilateral periventricular, centrum semi ovale elliptical T2 hyperintensity is oriented alon Dawson's fingers typical of the demyelination. AARGH...

check this link for great presentation on D fingers

this is better to see the dawsons fingers mechanics

on the simka website under dawsons fingers...the animation suggests Jugular veins may be the cause.

Another lesion pattern from Schelling's book...also related to blood vessels-

Steiner's Lesion Sketches
In 1931 Gabriel Steiner, at the University of Heidelberg, drew vivid pictures of the spread of multiple sclerosis into the cerebral hemispheres. Apart from presenting schematic drawings of process-typical intrusions into the cerebral cortex from its outer side, he illustrated impressively the specific plaques' bumpy, stalked or splashy projections off the ventricular borders. Because the lesion formations preferentially burst forth at the lateral cerebral ventricles' outer angles, this site was referred to by the telling German name "Wetterwinkel", denoting a source of thunderstorms and deluges. This site has also come to be known as "Steiner's Wetterwinkel". All in all, Steiner's pictures lucidly highlighted what Dawson's description of cerebral multiple sclerosis had disclosed fifteen years before (134).
In 1962 Steiner, then at Wayne State University, demonstrated again that cerebral multiple sclerosis is primarily characterized by smooth, rounded or peaked lesions rising off of the ventricular border. Besides showing that ventricle-based lesion “tongues” can also connect with more peripheral plaques, Steiner now observed that isolated, ovoid or spherical lesion "splashes" also arise from blood-vessels far away from the ventricles (135). Such separate plaques are here referred to as "Steiner's splashes".


I love Schelling's writing...very descriptive, and gives such good historical information on MS research.
Jeff's lesions are not typical Dawson's Fingers (elongated) but rather small, spread out and round...twenty of these "splashes" in his brain. These lesions arise from blood vessels further from the ventricles.
