Migraine with aura, not intractable, without status migrainosus [G43.109], Reason for Study: ^Reason: chronic HA, eval for parenchymal or demyelinating disease History: chronic HA, eval for parenchymal or demyelinating disease No evidence of acute ischemic or hemorrhagic lesion.The ventricles, sulci and cisterns are symmetric and unremarkable. The gray-white matter differentiation is normal. 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.
No evidence of acute ischemic or hemorrhagic lesion.No evidence of abnormal signal intensity on FLAIR/T2 weighted image indicating possible demyelinating disease.
