NONCONTRAST CT HEADSubtle low attenuations on the right basal ganglia and right temporal lobe which are compatible with evolving acute ischemic infarct. There is no evidence of hemorrhagic transformation. No change of linear encephalomalacia seen on the right cerebellar hemisphere since prior scan. The ventricles, sulci, and cisterns are symmetric and unremarkable. The osseous structures are unremarkable. The paranasal sinuses and mastoid air cells are clear. CTA HEAD AND NECKThe right internal carotid artery at the level of proximal cavernous sinus segment to the level of supraclinoid segment is not visualized. Detailed source imaging evaluation showed tubular intravascular filling defect indicating possible intra-arterial thrombus. Other possibilities include diffuse arterial luminal stenosis which is less likely. Right ophthalmic artery is reconstituted through external carotid collateral, right MCA appear to be reconstituted through the flow via the right Posterior communicating artery. However, the distal right MCA M1 segment is not clearly shown indicating another tandem intra vascular thrombus. There is normal aortic arch origin of the right brachiocephalic, left common carotid, and left subclavian arteries. The bilateral vertebral artery origins are normal. There is large atheromatous plaque with a very severe on the left carotid bulb. Normal contrast opacification through the right common carotid artery. There is normal contrast opacification through bilateral MCAs and ACAs. Vertebrobasilar system appears to be normal. Bilateral Pcom arteries are patent and Acom artery is also patent. No evidence of aneurysm, dissection, or vascular malformation is noted. There is normal superficial and deep intracranial venous drainage.
