Persistent migraine aura without cerebral infarction, not intractable, without status migrainosus [G43.509], Reason for Study: ^Reason: vision changes with headache History: vision changes There is no evidence of acute ischemic or hemorrhagic lesion.There is no evidence of abnormal enhancement.Polypoid soft tissue lesion on the posterior aspect of nasal cavity which appears to be connected to the left inferior turbinate posterior aspect with homogenous enhancement. This lesion suggest possible nasal polyposis, thus clinical correlation/inspection is recommended. 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, restricted diffusion/acute ischemia, or intracranial abnormal contrast enhancement. The midline structures and cranial-cervical junction are normal. Normal flow voids are identified in the major intracranial vessels. The mastoid air cells are clear.
1. No evidence of acute ischemic or hemorrhagic lesion.2. No abnormal enhancement intracranially.3. Possible nasal polyposis especially left inferior posterior turbinate, clinical correlation is recommended.
