Unspecified visual loss [H54.7], Reason for Study: ^Reason: embolic stroke History: left weakness acute onset with hypodensity on CT Brain MRIThere is no evidence of acute ischemic or hemorrhagic lesion.There is focal FLAIR high signal intensity on the right external capsule anterior aspect, which is non specific but could be small vessel ischemic disease. Suspicious low attenuation seen on the right parietal lobe on CT scan is not seen on this scan, thus was an artifact.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. The midline structures and cranial-cervical junction are normal. 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.Right Pcom artery and Acom artery are patent.There is no intracranial aneurysm. No intracranial arterial luminal stenosis.Neck MRA3D MRA neck post-gadolinium images with maximum intensity projections of the cervical vasculature demonstrate 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 common carotid, carotid bifurcations, internal/external carotid, and vertebral arteries. There is no evidence of arterial luminal stenosis or irregularity.C-Spine MRIThere is normal cervical lordosis. The cranial-cervical junction is normal. Spinal cord signal intensity is normal. Surrounding soft tissue appears to be normal.There is diffuse bulging of disc with moderate right side neuroforaminal stenosis at the level of C34. There is central focal bulging of disc at the level of C56. Otherwise no remarkable finding.
1. No evidence of acute ischemic or hemorrhagic lesion.2. Focal FLAIR high signal intensity lesion on the right external capsule anterior aspect is non specific.3. Normal brain and neck MRA.4. Normal spinal cord signal intensity.5. Diffuse bulging of disc with moderate degree right side neuroforaminal stenosis at the level of C34.
