Altered mental status, unspecified [R41.82], Reason for Study: ^Reason: ischemic stroke History: R sided weakness Brain MRIThere is no evidence of acute ischemic or hemorrhagic lesion.Patchy bilateral somewhat confluent T2/FLAIR high signal intensity periventricular white matter and centrum semiovale indicate nonspecific small vessel ischemic disease.There are multiple lacunar infarctions on bilateral basal ganglia and left cerebellar hemisphere.The ventricles, sulci and cisterns are symmetric and unremarkable. The gray-white matter differentiation is normal. There is no mass, mass effect, edema, midline shift, intra or extra-axial fluid collection/hemorrhage. The midline structures and cranial-cervical junction are normal. Normal flow voids are identified in the major intracranial vessels. The paranasal sinuses are clear.Bilateral mastoid air cells show opacification.Brain MRA3D time of flight MOTSA MRA brain images with maximum intensity projections of the anterior/posterior intracranial circulation demonstrate normal ICAs, MCAs and ACAs. Vertebrobasilar system appears to be normal.Neck MRA3D MRA neck post-gadolinium images with maximum intensity projections of the cervical vasculature demonstrate normal flow enhancement in a normal aortic arch origin of the right brachiocephalic, left common carotid, and left subclavian arteries. The vertebral artery origins are normal. There is normal flow enhancement through the bilateral common carotid, carotid bifurcations, internal/external carotid, and vertebral arteries.
1. No evidence of acute ischemic or hemorrhagic lesion.2. Non specific small vessel ischemic disease.3. No evidence of arterial luminal stenosis on craniocervical arterial system.4. No intracranial arterial aneurysm.
