Dizziness and giddiness [R42], Reason for Study: ^Reason: vertigo, history of CVA, please eval History: vertigo, history of CVA, please eval There is no evidence of acute ischemic or hemorrhagic lesion.There are multifocal tissue losses involving bilateral basal ganglia and thalami indicating chronic lacunar infarctions.Multifocal patchy scattered high signal intensity lesions on bilateral periventricular white matter and centrum semiovale indicate non specific small vessel ischemic disease. Unchanged since prior scan.The ventricles, sulci and cisterns are symmetric and unremarkable. The gray-white matter differentiation is normal. 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. Normal flow voids are identified in the major intracranial vessels. The mastoid air cells are clear.Mucosal thickenings on bilateral maxillary sinuses and a retention cyst in the right maxillary sinus.
No evidence of acute ischemic or hemorrhagic lesion.Mild to moderate non specific small vessel ischemic disease, no change since prior scan.
