Altered mental status, unspecified Altered mental status, unspecifiedClinical question: r/o acute findingsSigns and Symptoms: altered mental status There is diffusion restriction present along the splenium of the corpus callosum as well as the thalami bilaterally and symmetrically.There are subdural effusions present bilaterally.. Exam is mildly degraded by patient motion.There is some retropharyngeal soft tissue thickening present. This finding has been present on prior soft tissues of the neck studies.There is mild patchy T2 signal hyperintensity present within the brain stem.The patient is status post cholecystectomy and head and neck surgery.No abnormal 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 some mucosal thickening in the sphenoid sinuses. The visualized portions of the mastoid air cells demonstrate partial opacification of the right mastoid air cells and to a lesser degree left mastoid air cells.. The visualized portions of the orbits are intact.
1.Diffusion restriction symmetrically within the splenium and thalami is present. This can be seen with the encephalitis, influenza as well as warning cues encephalopathy (thiamine deficiency) in the appropriate clinical setting.2.There are small subdural effusions present intracranially as etiology is uncertain on the basis of this exam..
