Migraines can be notorious for never pinpointing cause/effect. For some people they can have clearly identifiable triggers ie smells, bright lights etc, but for some finding those triggers can be near on impossible.
It’s similar for the type of migraine that presents. Some can be ocular in location, but the actual cause not be ocular at all. My eyes are where I feel heaps of pain. At times I feel my eyeballs are going to explode from my skull, the pressure behind them is just MASSIVE. And yet my issue has nothing to do with my eyes, nor my visual cortex. As the growth in my head has expanded it has put pressure on differing brain structures and it seems this is the source of my ongoing pain. Now this is one dr’s theory. But there are other theories such as a spinal issue, a tension issue, a chemical imbalance, a posture issue etc, etc, etc
A craniotomy is a major assault on the brain. Our skulls are hard, solid bone for a reason, to protect all of those delicate circuits within the grey matter. Along comes a surgeon who opens that protective skull and disturbs those fine circuits, there simply has to be a flow on effect. I sometimes explain it like this:
“If you opened your computer box and threw in a hand full of alfoil flakes, what would happen? Your computer system would have short circuits all over the place and that’s if the system ever worked properly again”
By disturbing those fine circuits, that can have the same sort of a effect on our brains.
As for your report, this is something that really has to be explained by a neuro but a big plus to take from it is "…but it not clearly fistulous or early filling.” In really basic terms a fistula is like a vessel blowing out the side. Where it bulges the wall becomes thinner and is a risk as a weak point. There’s no sign of that. And no sign of ‘early filling’, the early sign of a weakness. So that’s a good thing.
But again trying to draw a straight line between the report and symptoms needs to be discussed and investigated by your neuro.
Hope it helps
