Anyone who have been a long-term reader of the blog know that every now and then a character comes along who likes to challenge the team. The nemesis of TeamG and the peoples champion who wants to “Stick it to the man” We get Sid from the Cup (Siddcup) and then we had DrDre the rapper from Bradford . ProfG used to get his character assassinated by Joanie and for those with a distant memory we had VV/ Vasillis Vasilopulous from Greece, who used to take us to task about not believing CCSVI, VV loved his back jets…and his Dawsons fingers. What are Dawsons fingers?
What may offend a Brit is just a victory sign to thers but a Dawsons fingers are are a radiographic feature of demyelination characterised by periventricular demyelinating plaques distributed along the axis of medullary veins, perpendicular to the body of the lateral ventricles and/or callosal junction.
I used to think of them of inflammation along a blood vessel, but VV had them cback jets due to the pressure from blocked veins
Dawson fingers are used to differentiate multiple sclerosis (MS) from other conditions that affect the subcortical white matter. However, there are no studies evaluating the presence of Dawson fingers in subjects with cerebral small vessel disease (cSVD). We aimed to assess prevalence and -correlates of Dawson fingers in older adults with cSVD-related moderate-to-severe white matter hyperintensities (WMH). Community-dwelling older adults residing in rural Ecuador – identified by means of door-to-door surveys – underwent a brain MRI. Exams of individuals with cSVD-related moderate-to-severe WMH were reviewed with attention to the presence of Dawson fingers. Of 590 enrolled individuals, 172 (29%) had moderate-to-severe WMH. Of these, 18 (10.5%) had Dawson fingers. None had neurological manifestations suggestive of MS. Increasing age was independently associated with Dawson fingers (p = 0.017). Dawson fingers may be less specific for MS than previously thought. Concomitant damage of deep medullary veins may explain the presence of Dawson fingers in cSVD.

Was it back jets after all;-)
