Dizziness and giddiness [R42], Reason for Study: ^Reason: etiology of vertigo spells History: dizziness spells Brain MRIThere is no evidence of acute ischemic or hemorrhagic lesion.Scattered multifocal bihemispheric periventricular white matter and centrum semiovale T2/flair high signal intensity lesions are seen. These lesions are nonspecific likely represent nonspecific small vessel ischemic disease. Comparing to prior scan, the number and extent of high signal intensity lesions appear to be increased slightly.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. The midline structures and cranial-cervical junction are normal. The paranasal sinuses and mastoid air cells are clear.Brain MRA3D time of flight MOTSA MRA brain images with maximum intensity projections of the anterior/posterior intracranial circulation demonstrate normal ICAs, MCAs and ACAs. Vertebrobasilar system appears to be normal. Specifically, there is no evidence of arterial luminal stenosis or intracranial arterial aneurysm.
1. No evidence of acute ischemic or hemorrhagic lesion.2. Slight interval progress of T2/flair high signal intensity lesions which likely represent nonspecific small vessel ischemic disease on bilateral periventricular white matter and centrum semiovale since prior scan. 3. No evidence of significant intracranial arterial luminal stenosis. No evidence of intracranial arterial aneurysm.
