Cerebral infarction, unspecified [I63.9], Reason for Study: ^Reason: eval for vessel narrowing/pathology given evidence of ischemic CVA History: eval for vessel narrowing/pathology given evidence of ischemic CVA on head CT Brain MRI:Multifocal bihemispheric acute ischemic infarct including right frontal lobe, right caudate nucleus head, right occipital lobe and left posterior temporal lobe. On gradient echo technique, there are subtle blooming artifacts on the right frontal lobe acute ischemic infarct lesion indicating possible hemorrhage transformation.The ventricles, sulci and cisterns are symmetric and unremarkable. 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.
1. Multifocal bihemispheric acute ischemic infarcts as described above with possible focal hemorrhagic conversion especially on the right frontal lobe lesion.2. Normal brain MRA.
