Speech disturbance, altered consciousness. There is restricted diffusion on the left side of pons indicating acute ischemic stroke.On the right side pons, there are a couple of focal tissue loss indicating prior ischemic stroke.There is no evidence of acute hemorrhage lesion on the scan.Patch bilateral high signal intensities on FLAIR imaging on periventricular white matter indicate nonspecific small vessel ischemic disease.There are multiple scattered bihemispheric round low signal intensities on gradient echo scans indicate either brain calcifications or chronic hemorrhagic foci.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.
Acute ischemic infarct, left side of pons without evidence of hemorrhagic transformation.Nonspecific small vessel ischemic disease.
