Headache [R51], Reason for Study: ^Reason: headache.dizzy, no proprioception History: headache,dizzy, no proprioception Brain MRINo evidence of acute ischemic or hemorrhagic lesion.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 mastoid air cells are clear. There are mucosal thickening on bilateral ethmoid sinuses (left worse than right).Brain MRAMotion artifacts degraded exam quality.3D time of flight MOTSA MRA brain images with maximum intensity projections of the anterior/posterior intracranial circulation demonstrate bilateral fetal PCAs and normal ICAs, MCAs and ACAs. Vertebrobasilar system appears to be normal.For more definitive evaluation of intracranial arterial aneurysm or significant (more than 50%) luminal stenosis.Neck MRA3D MRA neck post-gadolinium images with maximum intensity projections of the cervical vasculature demonstrate about 10% luminal stenosis at the level of the right carotid bulb. Otherwise normal flow enhancement in a normal aortic arch origin of the right brachiocephalic, left common carotid, and left subclavian arteries. The vertebral artery origins are normal. There is normal flow enhancement through the bilateral internal/external carotid, and vertebral arteries. Vertebrobasilar system appears to be smaller in lumen size, however, given circumstances of bilateral fetal PCAs, this should be interpreted as a normal disposition of posterior fossa circulation.
