Dizziness and giddiness [780.4], Reason for Study: ^Reason: c/f acute CVA, new dizziness (pre-syncope, dysequilibrium) History: see above There is no evidence of acute ischemic or hemorrhagic lesion on the scan.Multifocal scattered patchy high signal intensities on FLAIR imaging on bilateral periventricular white matter indicate nonspecific small vessel ischemic disease.There is a focal increased signal intensity on the right basal ganglia likely involving anterior limb of internal capsule and globus pallidus may indicate age-indeterminate likely chronic ischemia.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, or restricted diffusion/acute ischemia. 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.
1. No evidence of acute ischemic or hemorrhagic lesion.2. Nonspecific small vessel ischemic disease.3. Chronic ischemic lesion on the right basal ganglia.
