Female, 60 years old, with history of grade 2 oligodendroglioma, off all therapy now, status post RT/PCV. Ill-defined T2 hyperintense signal abnormality involving the left temporal lobe shows no significant change in overall size or geographic extent. Gyriform T1 hyperintensity and susceptibility likely reflect mineralization of the lesion. No evidence of mass effect or clear pathologic enhancement is observed.A nonspecific subcentimeter focus of nonenhancing T2 signal abnormality is unchanged in the right cerebellum. Ill-defined T2 hyperintensity within the left corona radiata and periatrial tissue is similar to the immediate prior examination. No new enhancing lesions are seen. Ventricular size and morphology are unchanged.
Stable findings are seen compatible with treated left temporal lobe tumor. No evidence of local progression is seen. No new intracranial lesions are observed.
