Weakness [R53.1], Reason for Study: ^Reason: eval for acute abnormalities History: facial droop, weakness Brain MRISignificant metallic artifacts especially right side degraded image quality especially right side posterior fossa.There is no evidence of acute ischemic or hemorrhagic lesion on the scan.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. Normal flow voids are identified in the major intracranial vessels. 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.No evidence of intracranial arterial aneurysm or significant stenosis.The left lens is not seen indicating postoperative status.
