Unspecified visual disturbance [368.9], Reason for Study: ^Reason: cause of vision loss History: vision loss Brain MRI:There is no evidence of acute ischemic or hemorrhagic lesion.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. Normal flow voids are identified in the major intracranial vessels. The paranasal sinuses and mastoid air cells are clear.Neck MRA:3D 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. Brain MRV3D MRV brain post-gadolinium with maximum intensity projections of the superficial/deep intracranial venous drainage demonstrate normal flow enhancement in the superior sagittal sinus, transverse sinuses, sigmoid sinuses, internal cerebral veins, vein of Galen and straight sinus.Orbit MRIThere is pre-septal soft tissue swelling which shows high signal intensity on T2 weighted image and enhancement indicating possible cellulitis.The globes, optic nerves, extraocular muscles and retroglobal spaces are symmetric and normal. The lacrimal glands are normal.
1. No evidence of acute ischemic or hemorrhagic lesion on this scan.2. Normal brain MRI, Neck MRA and Brain MRV.3. Possible pre-septal cellulitis on the right as described above.
