Cerebral infarction, unspecified [I63.9], Reason for Study: ^Reason: stroke workup History: left sided weakness and numbness Brain MRIThere is no evidence of acute ischemic lesion.A small susceptibility lesion on the left thalamus is seen indicating chronic petechial hemorrhage or mineralization, unchanged since prior scan.Multifocal bihemispheric scattered T2/FLAIR high signal intensity lesions seen on bilateral periventricular white mater and centrum semiovale. These lesions are non specific, unchanged since prior scan. 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. The midline structures and cranial-cervical junction are normal. The paranasal sinuses and mastoid air cells are clear.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 and hemorrhagic lesion.2. Nonspecific white mater T2/FLAIR high signal intensity lesions, unchanged since prior scan.3. No evidence of arterial luminal stenosis on both intracranial and extracranial arterial system. No intracranial aneurysm.
