Clinical question: Stroke. Signs and symptoms: Stroke. Nonenhanced CT of brain:The examination demonstrates fairly extensive supratentorial periventricular and subcortical low-attenuation with no associated mass effect. There is also suspected low-attenuation of corpus callosum. Although the above findings are nonspecific they could represent very advanced to small vessel disease of indeterminate age. Findings remain identical to prior study from 6 -- 2 -- 2010. Follow-up with an MRI examination is recommended to exclude other possibilities. Multiple prior studies and including patient MRI examination from 2009 demonstrated similar findings.An old right posterior temporal -- parietal cortical stroke is again identified and no change.Images through posterior fossa demonstrate suspected low-attenuation in the pons consistent with old lacunar strokes.There is no evidence of hemorrhage or acute cortical stroke. The ventricular system remains within normal range of size.
1.Stable exam since prior study.2.Extensive White matter findings likely secondary to advanced to small vessel disease of indeterminate age.3.Old right posterior parietal -- temporal cortical stroke. Local nor strokes of pons.
