Muscle weakness (generalized) [M62.81], Reason for Study: ^Reason: assess for stroke and/or optic nerve lesion History: visual field defect and left sided weakness Brain MRINo evidence of acute ischemic or hemorrhagic lesion.No evidence of abnormal enhancement.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. The mastoid air cells are clear.Mucosal thickenings on bilateral ethmoid sinuses and a retention cyst on the right maxillary sinus.Pineal gland calcifications are seen.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.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. Orbit MRIMotion artifact degraded exam quality. The globes, optic nerves, extraocular muscles and retroglobal spaces are symmetric and normal. The lacrimal glands are normal. There is no evidence of signal abnormality, mass, or abnormal contrast enhancement.
1. No evidence of acute ischemic or hemorrhagic lesion. No abnormal enhancement.2. Normal brain MRA, normal neck MRA.3. Unremarkable orbit MRI.
