Female, 72 years old, with new right lower extremity weakness. Assess for etiology. A subcentimeter focus of diffusion restriction is seen within the left corona radiata immediately adjacent to the body of the left lateral ventricle. Correlating ADC abnormality has nearly resolved. This lesion is associated with corresponding T2 hyperintensity. Also noted is T2 hyperintensity just below within the posterior limb of the left internal capsule.Numerous patchy areas of T2 hyperintensity are seen within the periventricular white matter bilaterally. No significant parenchymal edema or mass effect is detected. No intracranial hemorrhage or any abnormal extra-axial fluid collection is detected. The ventricles and sulci are mildly prominent compatible with underlying parenchymal volume loss.
1.Small area of ischemia within the left corona radiata, likely late subacute, potentially affecting the left corticospinal tract. No significant associated edema or hemorrhage is detected. Findings were discussed with Dr. Hong at approximately 3:00 PM on 10/26/2015.2.Evidence of moderately extensive chronic small vessel ischemic disease.
