NONCONTRAST CT HEADNo evidence of acute ischemic or hemorrhagic lesion on this scan. The ventricles, sulci, and cisterns are symmetric and unremarkable. The gray-white matter differentiation is normal. There is no mass effect, edema, midline shift, intra- or extra-axial fluid collection or acute hemorrhage. The osseous structures are unremarkable. The paranasal sinuses and mastoid air cells are clear. CTA HEAD AND NECKThe right vertebral artery appears to be small in diameter from its ostium to the level of right vertebrobasilar junction. This indicate possible hypoplastic right vertebral artery instead of diffuse dissection. The left vertebral artery is dominant with normal vascular luminal size without evidence of stenosis. There is normal aortic arch origin of the right brachiocephalic, left common carotid, and left subclavian arteries. The left vertebral artery origin is normal. There is normal contrast opacification through the bilateral common carotid arteries, carotid bifurcations, cervical internal or external carotid, and vertebral arteries. There is normal contrast opacification through bilateral ICAs, MCAs and ACAs. Vertebrobasilar system appears to be normal. Bilateral Pcom arteries are patent and Acom artery is also patent. No evidence of aneurysm, significant stenosis, occlusive thrombus, dissection, or vascular malformation is noted. There is normal superficial and deep intracranial venous drainage.
