CTA performed from arch to circle of Willis demonstrates normal arterial structures. Three vessel arch anatomy is present. The carotid arteries and vertebral arteries are widely patent. No significant narrowing is seen.
Incidental note is made of fetal origin of the right posterior cerebral artery. The posterior circulation is otherwise unremarkable. The carotid arteries, middle cerebral arteries and anterior cerebral arteries bilaterally are patent.
1. Evidence of bilateral deep venous infarcts with hemorrhage on the right and associated hydrocephalus either due to congestion or compression of the third ventricle as well as evidence of cerebral edema.
2. Straight sinus thrombosis with likely extension into the left transverse sinus.
3. Possible focal thrombosis of the superior left internal jugular vein.
