I’ve never really studied blood test stuff so I’m not any good at it, sorry There’s a danger with googling these too as different labs have different ways of doing tests so that the results may look normal/abnormal but actually be the opposite.
The positive oligoclonal bands result can support a diagnosis of MS, but it also happens in lots of other conditions and it’s possible to get a false positive. Fwiw, however, this lists the normal ranges of the CSF results: http://www.osceskills.com/e-learning/subjects/cerebrospinal-fluid-results-interpretation/ (please bear in mind the different labs thing though!).
From this, and assuming that the 92 red cells means 92 x 106 (which it might NOT!), it looks like it might point towards a subarachnoid haemorrhage. But then, wikipedia (not exactly a great source mind you!) suggests that 92 is too low for a subarachnoid haemorrhage. Another source (http://www.dartmouth.edu/~dons/part_1/chapter_11.html) says that a cerebral haemorrhage that leaks into the subarachnoid space can also cause red blood cells in the CSF. Would this maybe cause a lower red cell count than a subarachnoid haemorrhage???
A subarachnoid/cerebral haemorrhage MIGHT fit with the “fuzzy” lesion: MS lesions tend to have nice clean edges whereas strokes and vascular stuff often cause fuzzy edges, but I would hope the radiologist would have recognised a haemorrhage if there was one, and reported it as a possibility.
I also found this though: http://www.gpnotebook.co.uk/simplepage.cfm?ID=-1469382612. It says that subarachnoid haemorrhage can cause a positive oligoclonal bands result.
All of which probably only shows that using Dr Google is a dangerous path to tread - because it puts ideas in our heads that may subsequently prove to be complete rubbish!!! (Btw, apparently a subarachnoid haemorrhage starts with a sudden killer of a headache.)
Sorry, this is probably more confusing than helpful! It might be worth asking the neuro about the red cell count though? (It wouldn’t be high in MS I don’t think.)
And just as I was about to click on post, it occurred to me that you might not know what subarachnoid/cerebral haemorrhages are. As far as I know, they are like a burst blood vessel. The arachnoid is one of the membranes / linings surrounding the brain. The subarachnoid space is the gap between the brain and the arachnoid. So a subarachnoid haemorrhage is a burst blood vessel in that space. A cerebral haemorrhage is a burst blood vessel in the brain.
