Cerebral infarction due to unspecified occlusion or stenosis of unspecified cerebellar artery [I63.549], Reason for Study: ^Reason: acute ischemic stroke History: Increased left arm/leg weakness from baseline There are restricted diffusion lesions on the right periventricular white matter indicate acute ischemic infarction. Scattered susceptibility artifacts within the restricted diffusion lesions on gradient echo images indicate possible hemorrhagic conversion.Minimal FLAIR high signal intensity lesion on periventricular white matter indicate non specific small vessel ischemic disease.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 are clear.Near complete opacifications on the right mastoid air cells and partial opacifications on the left mastoid air cells are seen.
1. Acute ischemic infarction with focal hemorrhagic conversion on the right basal ganglia and corona radiata.2. Non specific small vessel ischemic disease.
