Transcript: Okay, vascular lesions. So just like in adults, you can have cortical and medullary vein thrombosis, but neonates are more predisposed to pro-thrombotic conditions from the birth, from sepsis, from hypoxia, ischemia, all of these things.
So you really want to make sure that this is a high-level suspicion because I think this case was called trauma by an adult radiologist, right?
And it's like, yes, there is diffuse hypoxia and there's a lot of peripheral.
But, I mean, there aren't any subdurals, right? And it's like, what is this?
So basically there was diffuse venous sinus thrombosis, and then you had secondary arterialization, because if you get the impaired venous outflow over time, the pressures build up and then you get little petechial hemorrhages, right?
The capillaries rupture, and then the pressures get so high for venous outflow that you start to get secondary arterialization.
So there's no, you know, large artery distribution because the entire brain is infarcting, right from a long-standing venous thrombosis. So it's very important to remember this diagnosis.
