Weakness [R53.1] / Cerebral infarction due to unspecified occlusion or stenosis of left middle cerebral artery [I63.512], Reason for Study: ^Reason: stroke History: weakness There are restricted diffusion areas on the left frontal operculum indicating acute ischemic infarct. There is no evidence of hemorrhagic conversion.Underlying brain shows scattered high signal intensity lesions on periventricular white matter and centrum semiovale, suggesting underlying nonspecific small vessel ischemic disease.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. Normal flow voids are identified in the major intracranial vessels. The paranasal sinuses and mastoid air cells are clear.
Acute ischemic infarct, left frontal operculum without evidence of hemorrhagic conversion.Underlying nonspecific small vessel ischemic disease, minimal to mild.
