Diagnosis: Syncope and collapseClinical question: mass or atrophy causing memory problemsSigns and Symptoms: dementia The CSF spaces are appropriate for the patient's stated age with no midline shift. No abnormal enhancing mass lesions are appreciated intracranially. No intracranial hemorrhage is identified. No edema is identified within the brain parenchyma.Normal vascular flow voids are present in the distal carotid and vertebral arteries, the basilar artery and the proximal anterior, middle and posterior cerebral arteries as well as the internal cerebral veins and superior sagittal sinus.The visualized portions of the paranasal sinuses demonstrate air-fluid level and mucosal thickening in the left maxillary sinus and a minor opacity in the right maxillary sinus as well as partial opacification of the left ethmoid air cells.. The visualized portions of the mastoid air cells are clear. The visualized portions of the orbits are intact.Some images are degraded by motion artifact
No obvious explanation for the patient's and dementia can be ascertained on the basis of this exam.Pattern of low opacification of paranasal sinuses may suggest obstruction at the level of the left hiatus semilunaris.Exam is degraded by patient motion which may obscure more subtle abnormalities.
