What are these MRI images consistent with? {{c1::Dural and deep cerebral venous thromboses.}}

This child became dehydrated and developed dural and deep cerebral venous thrombosis.
The abnormal findings of enlarged arterial flow voids are absent on MR, so arteriovenous malformation (AVM) is not plausible.
The findings are not supportive of nonaccidental trauma, as there are no extraaxial collections; nor are there clinical features to suggest this.
This child did well with treatment, and the follow-up imaging was normal with recanalization of the thrombosed venous structures.
The outcome may be fatal (8% of neonatal cases); up to 50% will develop venous infarct.
This is not a normal variant.
