Hemiplegia, unspecified affecting unspecified side [G81.90], Reason for Study: ^Reason: Evaluate for ischemia History: R hemiparesis, has history of MS Motion artifact degraded exam quality.There is no evidence of acute ischemic lesion.Susceptibility artifacts are seen along the course of left circumflex thalamic stimulator, however, otherwise there is no MR evidence suggesting acute hemorrhagic lesion.Multifocal patch high signal intensity lesions involving bilateral periventricular white matter, centrum semiovale as well as posterior fossa are compatible with demyelinating disease such as multiple sclerosis.The ventricles, sulci and cisterns are symmetric and unremarkable. There is no mass, mass effect, edema, midline shift, intra or extra-axial fluid collection. 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 lesion on this scan.2. Susceptibility artifacts are seen along the course of the left thalamic stimulator, however, there is no other MR lesion suggesting acute hemorrhagic lesion on this scan.3. White matter lesions are consistent with multiple sclerosis.
