Unspecified cerebral artery occlusion with cerebral infarction [434.91], Reason for Study: ^Reason: stroke History: stroke There is no evidence of acute ischemic or hemorrhagic lesion on this scan.Multifocal scattered high signal intensities on FLAIR images indicate non specific small vessel disease.Multifocal high signal intensities on the left pons and left middle cerebellar peduncle indicate chronic ischemic infarctions with tissue losses.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, restricted diffusion/acute ischemia, or abnormal contrast enhancement. 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.There is a right frontal burr hole. 3D time of flight MOTSA MRA brain images with maximum intensity projections of the anterior/posterior intracranial circulation demonstrate slightly ectatic bilateral ICA cavernous sinus and paraclinoid segments indicating atherosclerotic changes. There is no intracranial arterial aneurysm. There is no intracranial arterial luminal narrowing or irregularity.
1. No evidence of acute ischemic or hemorrhagic lesion.2. Non specific small vessel ischemic disease.3. Atherosclerotic changes of bilateral cavernous sinus and paraclinoid segments of ICAs as described above. Otherwise unremarkable.
