Unspecified cerebral artery occlusion with cerebral infarction [434.91], Reason for Study: ^Reason: STROKE History: R SIDE WEAKNESS Scattered restricted diffusion lesions on the left PCA territory including left occipital lobe, left side corpus callosum splenium, left thalamus, and left periventricular white matter. In addition, there are scattered restricted diffusion lesions on the right parietal lobe and bilateral cerebellar hemispheres.There is no evidence of hemorrhagic transformation.Underlying brain shows extensive patchy high signal intensities on periventricular white matter, cerebellar hemisphere and pons indicating non specific small vessel disease.In addition, there are multifocal tissue losses on bilateral basal ganglia and pons indicating chronic lacunar infarctions with encephalomalacia.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.
1. Multifocal acute/subacute ischemic infarctions mainly on the left PCA territory but also involves right parietal lobe and bilateral cerebellar hemispheres.2. There is no evidence of hemorrhagic transformation.3. Underlying brain demonstrated multifocal lacunar infarctions with tissue losses as well as extensive non specific small vessel disease.
