Dizziness and giddiness [R42], Reason for Study: ^Reason: Pt with acute onset of dizziness one week ago characterized as vertigo; initially 1.5 day duration, but no intermittent; rule out central cause History: see above There is no evidence of acute ischemic or hemorrhagic lesion on the scan.Scattered and somewhat patchy FLAIR high signal intensity lesions on periventricular white matter are nonspecific but could represent small vessel ischemic disease.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. Minimal nonspecific small vessel ischemic disease.
