I saw this too on twitter. Crazy stuff. I wonder if they had to do anything special with the MRI to see the microclots like dyes or mri settings or 7Tesla mri? Lots of ME/CFS patients have had MRIs for various reasons, this wouldn't have been missed in ME/CFS (if it occurs) unless it requires a different setup.
That looks like a standard 3T MRI brain with SWI sequence (susceptibility weighted imaging). It exaggerates artefact from haemosiderin, which is a blood break-down product. As you say, this is not something that would be missed in ME patients - it's far too obvious.
I don't speak Swedish, but the video this came from looks to be describing the result of COVID infection that wasn't severe enough to demonstrate lung changes on CT, but could show impaired gas transfer from lung to blood in discrete regions of the lungs. The remainder of the brain imaging shows significant abnormalities on other sequences also.
This isn't a mild COVID case. I'm presuming this is a result of "moderate+" COVID (even if clinically mild) and I would have thought these findings are unlikely to be seen in many such cases. I don't think microbleeds (which I'm assuming this pattern represents) are responsible for the vast majority of brain fog symptoms in LC. Also to me the time course to LC symptoms mimics typical ME onset and these marked imaging changes would be more likely present from the outset.
ETA: You can imagine a problem with the clinical stratification in COVID, when thinking of it as a pulmonary disease, not vascular. If lung impairment is sub-clinical, the patient might be thought "mild". Neuropsychiatric changes might be ignored as "pandemic anxiety" etc. Plenty of stories on Twitter of healthy people being discharged "well" and then going on to fatal or otherwise extreme post-covid psychosis.
