Multiple sclerosis [340], Reason for Study: ^Reason: MS, f/u progression History: paresthesias There is interval progression of the right frontal white matter lesion comparing to prior scan.Other scattered white matter lesions on bilateral hemispheres including bilateral frontal, parietal, temporal and occipital lobes, 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. Interval aggravation of the right frontal white matter lesion since prior exam.2. Other multiple scattered white matter lesions do not show any significant interval change since prior exam.
