Male, 71 years old, with slurred speech, CT concerning for stroke. Patchy foci of restricted diffusion are seen within the left posterior frontal and parietal lobes. Small foci are also seen in the left occipital lobe. There is mild edema associated with these lesions, along with mild gyriform enhancement. Elsewhere in the brain, numerous scattered foci of white matter T2 hyperintensity are seen. No evidence of significant parenchymal edema or mass effect is detected. No abnormal extra-axial fluid collections are seen. The ventricles are normal in size and morphology.The hyperattenuating lesion noted on prior CT within the left inferior frontal lobe is barely detectable on MRI as a focus of faint susceptibility and minimal if any T2 signal abnormality. The lesion does not enhance.
1.Scattered ischemic lesions within the left posterior frontal, parietal and occipital lobes which are likely subacute.2.No evidence of significant parenchymal edema or mass effect is seen.3.No intracranial hemorrhage is detected.4.A calcified lesion in the left inferior frontal lobe noted on prior CT is barely detectable on the present examination. The differential would continue to include a dystrophic calcification secondary to prior inflammation or infection, or perhaps a cavernoma.
