Female, 68 years old, history of GBM, now on temozolomide plus TTF. A lesion is redemonstrated involving the left inferior and middle frontal gyri with findings seen indicating prior biopsy or resection. Somewhat nodular foci of enhancement superficially along the operative site are unchanged. Deep to the resection site, a centrally nonenhancing lesion with ill-defined granular rim enhancement and some peripheral diffusion restriction is also unchanged. T2 hyperintensity which surrounds these lesions and spreads into the adjacent frontal and parietal lobes has not significantly changed.No new enhancing lesions are demonstrated. Multiple scattered small foci of white matter T2 hyperintensity are seen in the periventricular and subcortical regions without significant change. No abnormal extra-axial fluid collections are detected. The ventricles are stable and normal in size.
Stable enhancing lesions within the left inferior and middle frontal gyri with stable surrounding T2 signal abnormality.
