Dysarthria [784.51], Reason for Study: ^Reason: eval for vessel stenosis History: dysarthria, facial weakness? TIA work up There is no evidence of acute ischemic or hemorrhagic lesion on the scan.Several scattered bihemispheric periventricular white matter high signal intensity lesions on FLAIR imaging indicating nonspecific minimal small vessel ischemic disease.The ventricles, sulci and cisterns are symmetric and unremarkable. There is no mass, mass effect, edema, midline shift, intra or extra-axial fluid collection/hemorrhage, restricted diffusion/acute ischemia, or abnormal contrast enhancement. The midline structures and cranial-cervical junction are normal. Normal flow voids are identified in the major intracranial vessels. The paranasal sinuses and mastoid air cells are clear.3D 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. Bilateral posterior communicating arteries and anterior corticate and artery are patent.3D 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. There is no intracranial arterial aneurysm.There is no evidence of significant arterial luminal stenosis on both extracranial and intracranial arterial system.
1. No evidence of acute ischemic or hemorrhagic lesion on the scan.2. Minimal nonspecific small vessel ischemic disease.3. Normal brain and neck MR angiogram.
