Altered mental status, hallucinations. Visual tactile hallucinations. Significant metallic artifacts degraded nasopharynx, oropharynx and skull base area degraded image quality of these regions.There is no evidence of acute ischemic or hemorrhagic lesion.There is no evidence of abnormal enhancement.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.
Normal brain MRI.Significant metallic artifacts of naso, oropharynx and skull base area.
