Cerebral infarction, unspecified [I63.9], Reason for Study: ^Reason: assess for strokes History: right sided weakness Brain MRI:No evidence of acute ischemic or hemorrhagic lesion on this scan.There are focal tissue losses on the left basal ganglia and periventricular white matter with surrounding high signal intensities on FLAIR images indicating gliotic changes. Scattered high signal intensity lesions on bilateral periventricular white matter on FLAIR indicate minimal non specific small vessel disease.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, restricted diffusion/acute ischemia. 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.Brain MRA: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 PCAs are fetal origin.There is no evidence intracranial arterial aneurysm. No significant (more than 50%) luminal stenosis.Neck MRA: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. No acute ischemic or hemorrhagic lesion.2. Focal tissue losses on the left basal ganglia and periventricular white matter with surrounding gliotic changes.3. Minimal non specific small vessel ischemic disease.4. Normal brain MRA and neck MRA.
