Dysphagia, unspecified [R13.10], Reason for Study: ^Reason: compare to mri in pax History: opsoclonus Redemonstration of bilateral symmetric FLAIR/T2 high signal intensity lesions on anterior aspect of medulla without evidence of restricted diffusion or susceptibility artifact, unchanged since prior scan.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. Bilateral symmetric anterior medullary high signal intensity lesions, unchanged in their extent and MR characteristics since prior scan.2. No evidence of acute ischemic or hemorrhagic lesion on the scan.
