Diagnosis: Altered mental status, unspecifiedClinical question: r/o blood vessel irregularitySigns and Symptoms: nausea; lightheadedness The CSF spaces are appropriate for the patient's stated age with no midline shift. No abnormal mass lesions are appreciated intracranially. No intracranial hemorrhage is identified. No edema is identified within the brain parenchyma.A couple subcortical punctate T2 and FLAIR signal hyperintensities in the subcortical white matter of the left frontal lobe and left parietal lobe are probably of little clinical relevance given their small number and common occurrence in the general population.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 are clear. The visualized portions of the mastoid air cells are clear. The visualized portions of the orbits are intact.
MRI of the brain is within normal limits. There is no evidence for intracranial mass lesion or acute ischemic cerebral infarction.
