Vertebrobasilar occlusion, ataxia and leg weakness There are multiple restricted diffusion areas on the right middle cerebellar peduncle and right cerebellar hemispheres as well as pontomedullary junction indicating acute ischemic infarctions. Comparing to prior exam, these lesions are new ischemic infarctions.There is no evidence of hemorrhagic transformation.Multiple high signal intensity lesions on bilateral periventricular white matter and centrum semiovale on FLAIR images 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 and mastoid air cells are clear.
Multiple new acute ischemic infarction on the right cerebellum without evidence of hemorrhagic transformation as described above.Non specific small vessel ischemic disease.
