Altered mental status, visual hallucination. Evaluate for stroke. Nonenhanced head CT:CT is insensitive for detection of early acute strokes.There is no evidence of intracranial hemorrhage, edema, mass effect, midline shift or hydrocephalus.The cortical sulci and ventricular system as well as CSF cisterns are within normal limits.Very subtle periventricular and subcortical low attenuation of cerebral white matter is suspected of small vessel ischemic disease. These findings are significantly less noticeable on this study compared to prior MRI exam.Calvarium is intact. Visualized paranasal sinuses, mastoid air cells and orbits are unremarkable.
Very subtle findings of small vessel ischemic strokes of indeterminate age. Unremarkable exam otherwise.
