 There is a new focus of restricted diffusion with associated abnormal T2 signal within the right putamen adjacent to the posterior limb of the right internal capsule. This focus has faint enhancement on postcontrast imaging.There are post-surgical changes of a right temporoparietal craniotomy for partial tumor resection involving the right temporal lobe. Nodular enhancement surrounding the right temporal resection cavity as well as the right periatrial white matter is not significantly changed compared to the prior study. There is similar T2/FLAIR hyperintensity surrounding the resection cavity, but overall increased T2/FLAIR subcortical and periventricular hyperintensity, right greater than left. The ventricular size is unchanged. There is no midline shift.
1. Focus of restricted diffusion within the right putamen/posterior limb of the internal capsule with associated T2 signal abnormality and enhancement is suggestive of a subacute infarct.2. No significant change in enhancement surrounding the right temporal resection cavity. Increased white matter hyperintensity is favored to represent posttreatment change.Findings communicated via telephone to O. Kamson at 1244 hrs on 1/16/2016.
