Cerebral infarction, unspecified [I63.9], Reason for Study: ^Reason: acute stroke on ct History: hemiparesis Brain MRIThere are multifocal scattered restricted diffusion lesions involving bilateral cerebellar hemispheres, pons, left thalamus and right occipital lobe indicating acute ischemic infarctions. There is no evidence of hemorrhagic transformation.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.Brain MRA3D time of flight MOTSA MRA brain images with maximum intensity projections of the anterior/posterior intracranial circulation demonstrate occluded right ICA but patent and normal appearing left ICA, bilateral MCAs and bilateral ACAs. Bilateral PCAs are fetal origin.Vertebrobasilar system appears to be normal.
1. Multifocal acute ischemic infarctions involving bilateral cerebellar hemispheres, pons, left thalamus and right occipital lobe.2. Bilateral fetal PCAs. Otherwise no evidence of intracranial arterial stenosis or occlusion. No aneurysm was seen.
