atrophy and seconder enlargement of supratentorial ventricular system and sulkus means anything to anyone? I'm probably translating this wrong.
Nope - sounds like somethings got smaller which has caused something else to get bigger but that's s far as I get without a functioning brain myself.
As Wonko says, something has shrunk or atrophied, and the spaces (ventricles) have got larger as a result. Normally this would mean that it s the cerebral cortex that has got smaller. That occurs with time for all of us so the question is whether it is more than expected.
Does it note "unusual for age", @erin ? That's the kicker for mine (MRI); they tell you it's not kosher.
