Clinical question: Evaluate for etiology of altered mental status (metastases, CVA). Signs and symptoms cord altered mental status No evidence of hemorrhage, edema, mass-effect, midline shift or hydrocephalus. Extensive patchy periventricular and subcortical areas of low attenuation are nonspecific however likelihood of advanced small vessel disease should be considered. No evidence of cortical abnormality. Cortical sulci and ventricular system as well as the CSF cisterns are within normal range for patient's stated age.This examination cannot exclude metastatic lesion to the brain or leptomeninges without the benefit of contrast infusion. Further follow-up with an MRI is recommended. There is however no definitive evidence of metastatic disease on this non-infused study. Calvarial, paranasal sinuses and mastoid air cells are unremarkable.
1.Findings highly suspected off small vessel disease of indeterminate age.2.Limited value examination for dictation of metastatic disease due to lack of contrast. Follow-up with an MRI is recommended.3.Calvarium, paranasal sinuses and mastoid air cells are unremarkable.
