Right parietal ischemic stroke and a 60-year-old female. Images through posterior fossa demonstrates a focal area of low attenuation in the right aspect of pons with a small calcification. This is believed to represent an old lacunar infarct and dystrophic calcification. This finding was present on the prior exam and demonstrates no definitive interval change. To exclude other pathologies at this location an MRI exam is recommended.Images through the supratentorial brain parenchyma demonstrate no definitive evidence of stroke, hemorrhage, mass-effect or midline shift. A very subtle questionable lucency however overlapping the cortex of the operculum of the right parietal lobe is suspected on axial image 14 which was not present on the prior study. Further dilation with an MRI is recommended. This finding may represent a very small area of new cortical stroke.
1.Likely old lacunar infarct of the pons with calcification.2.Only suspect small lucency involving the cortex of the proximal right frontal lobe.3.Both these findings can be better evaluated with an MRI exam.
