Other headache syndrome [G44.89], Reason for Study: ^Reason: h/o migraine HA with pulsatile tinnitus and facial numbness, eval for vascular anomaly History: h/o migraine HA with pulsatile tinnitus and facial numbness, eval for vascular anomaly Brain MRIThere is no evidence of acute ischemic or hemorrhagic lesion on the scan.There is about 16.1 mm tonsilar ectopia through the foramen magnum level indicating Chiari 1 malformation. Ventricle size remains within normal limits.Prominent suprasellar cistern is also shown.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. The paranasal sinuses and mastoid air cells are clear.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.Bilateral Pcom arteries and Acom artery are patent.There is no intracranial arterial aneurysm. No significant arterial luminal stenosis.
1. Chiari 1 malformation as described above.2. No evidence of acute ischemic or hemorrhagic lesion.3. Normal brain MRA.
