Homonymous bilateral field defects, right side [H53.461] / Migraine with aura, not intractable, without status migrainosus [G43.109], Reason for Study: ^Reason: 74 year old female with old history of headaches, with acute onset of visual aura followed by No evidence of acute ischemic or hemorrhagic lesion.Few scattered FLAIR high signal intensity lesions on periventricular white matter indicate nonspecific small vessel ischemic disease. There is no evidence of abnormal enhancement.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, restricted diffusion/acute ischemia, or abnormal contrast enhancement. 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.Lens replacement on the right side.
1. No evidence of acute ischemic or hemorrhagic lesion.2. Nonspecific small vessel ischemic disease.3. No evidence of abnormal enhancement.
