Dysarthria following unspecified cerebrovascular disease [I69.922] / Essential (primary) hypertension [I10], Reason for Study: ^Reason: Concern for stroke History: As above There are new restricted diffusion lesions on the brainstem including right side of the lower midbrain, right side middle cerebellar peduncle, anterior aspect of lower pons, and right posterior aspect of medulla indicating acute ischemic infarct.Previously seen multifocal lower pontine and left middle cerebellar peduncle area restricted diffusion lesions has been decreased in signal intensity indicating normal evolution. There is no evidence of hemorrhage transformation.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. 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.
New acute ischemic infarcts on the brainstem as described above.Normal evolution of previously seen acute ischemic infarctions.No evidence of hemorrhagic transformation.
