Periodic headache syndromes in child or adult, not intractable [G43.C0], Reason for Study: ^Reason: migraines - r/o br cancer met, optic neuritis History: L eye pain Brain MRINo evidence of acute ischemic or hemorrhagic lesion.No evidence of abnormal enhancement, in particular, no definitive evidence of abnormal enhancement of optic apparatus.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 abnormal contrast enhancement. The midline structures and cranial-cervical junction are normal. The mastoid air cells are clear.Retention cyst on the left maxillary sinus.Brain MRA3D time of flight MOTSA MRA brain images with maximum intensity projections of the anterior/posterior intracranial circulation demonstrate normal ICAs, MCAs and ACAs. Vertebrobasilar system appears to be normal.There is the right side marginal tentorial artery seen (series 401, image 75) also known as the artery of Bernasconi and Cassinari, a normal meningeal arterial disposition.There is no evidence of intracranial arterial aneurysm or significant luminal stenosis.
1. No evidence of acute ischemic or hemorrhagic lesion. 2. No abnormal enhancement.3. Normal brain MRA
