Other convulsions [780.39], Reason for Study: ^Reason: r/o demyelinating disease, Do only sagittal FLAIR History: R leg weakness There are multifocal bihemispheric white matter high signal intensities on FLAIR imaging which do not show any significant interval changes in terms of size, number and extent since prior scan. Especially the the right periventricular and caudate nucleus lesion is perpendicular to the ventricular axis indicating possibility of demyelinating disease.There is no evidence of acute ischemic or hemorrhagic lesion on the scan.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. Multifocal bihemispheric various sized scattered high signal intensity lesions on FLAIR imaging indicating possible demyelinating disease, no change of the extent, number and distribution since prior scan.2. No evidence of acute ischemic or hemorrhagic lesion.
