Unspecified cerebral artery occlusion with cerebral infarction [434.91], Reason for Study: ^Reason: r/o stroke History: right hand weakness and numbness, transient aphasia Brain MRI:There band like restricted diffusion area on the left fronto-parietal operculum, most likely left subcentral lobule without evidence of hemorrhage, indicating acute ischemic stroke.Underlying brain shows scattered multifocal high signal intensities on FLAIR images on bilateral periventricular white matter indicate non specific 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. The midline structures and cranial-cervical junction are normal. 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.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.
1. Acute ischemic infarction without hemorrhagic transformation on the left fronto-parietal operculum, most likely subcentral lobule.2. Non specific small vessel ischemic disease.3. Normal brain MRA and normal neck MRA.
