Facial weakness [R29.810], Reason for Study: ^Reason: evaluate for brain stem infarct or tumor History: new right sided weakness, stroke risk factors, h/o malignancy No evidence of acute ischemic or hemorrhagic lesion.No evidence of abnormal enhancement.A couple of scattered FLAIR/T2 high signal intensity lesions on bilateral periventricular white matter is nonspecific, but could represent small vessel ischemic disease.The ventricles, sulci and cisterns are unremarkable. There is no mass, mass effect, edema, midline shift, intra or extra-axial fluid collection/hemorrhage, restricted diffusion/acute ischemia, or abnormal contrast enhancement. The midline structures and cranial-cervical junction are normal. Unusually enlarged distal vertebral arteries and basilar artery with a tortuous course indicating so-called vertebrobasilar dolichoectasia implying intracranial atherosclerotic disease. There is no evidence of significant (more than 50%) luminal stenosis.The mastoid air cells are clear.There is a retention cyst on the left maxillary sinus.
1. No evidence of acute ischemic or hemorrhagic lesion.2. Non specific small vessel ischemic disease.3. Vertebrobasilar dolichoectasia.
