Cerebral infarction, unspecified [I63.9], Reason for Study: ^Reason: left facial droop History: left facial droop Brain MRIThere is restricted diffusion lesion on the right internal capsule posterior limb without evidence of hemorrhagic conversion. Scattered multifocal T2/flair high signal intensity lesions on bilateral periventricular white matter and centrum semiovale indicating nonspecific small vessel ischemic disease are seen.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. Normal flow voids are identified in the major intracranial vessels. The mastoid air cells are clear. Mucosal thickening on the left maxillary sinus.Brain MRA3D time of flight MOTSA MRA brain images with maximum intensity projections of the anterior/posterior intracranial circulation demonstrate focal luminal stenosis at the proximal basal artery (about 60-70%).Otherwise, there is no evidence of intracranial arterial aneurysm. No other intracranial arterial luminal stenosis is seen.
1. Acute ischemic infarct involving right internal capsule posterior limb without evidence of hemorrhagic conversion.2. Nonspecific small vessel ischemic disease.3. Focal luminal stenosis of proximal basal artery (60-70%).
