Cerebral infarction, unspecified [I63.9], Reason for Study: ^Reason: assess for stroke History: R lower face droop and dysarthria Brain MRIThere is a focal restricted diffusion on the left internal capsule posterior limb. There is no evidence of hemorrhagic transformation.Patch bilateral periventricular and centrum semiovale T-2/FLAIR high signal intensity lesions indicate nonspecific small vessel ischemic disease. The ventricles, sulci and cisterns are 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.Brain MRA3D time of flight MOTSA MRA brain images with maximum intensity projections of the anterior/posterior intracranial circulation demonstrate focal luminal narrowing of the right MCA proximal M2 segment and left MCA distal M1 segment with luminal irregularity indicating atherosclerotic changes. Vertebrobasilar system appears to be normal.
1. Acute ischemic infarct involving left internal capsule posterior limb without evidence of hemorrhagic transformation.2. Atherosclerotic changes of intracranial arterial system. However, there is no evidence of intracranial large vessel occlusion. No evidence of intracranial arterial aneurysm.
