Female, 59 years old, history of grade 2 oligodendroglioma, status post RT and now status post cyclecycle #4 of PCV. Again seen is expansile T2/FLAIR hyperintensity involving the left temporal lobe including the left middle and inferior temporal gyri as well as the fusiform gyrus consistent with known tumor. Gyriform susceptibility effect within the lesion correlates to calcification noted on prior CT. Small focal area of enhancement within this lesion also remains unchanged. Sequelae of prior lesion biopsy are also again demonstrated. Focus of FLAIR hyperintensity in the left posterior frontal corona radiata is slightly more prominent and may represent posttreatment change.A subcentimeter nonenhancing focus of T2 hyperintensity within the right superior cerebellum is unchanged. No new or concerning parenchymal lesions are seen. No significant generalized mass effect is observed. The ventricles remain normal in size and morphologyy.
1.Compared to 4/1/2015 and 1/20/2016, there is no evidence of progression of the left temporal lobe oligodendroglioma. Increase in prominence of FLAIR hyperintensity in the left posterior frontal corona radiata may represent posttreatment change.2.Subcentimeter focus of T2 hyperintensity involving the right cerebellum remains unchanged since 5/9/2015. This lesion is nonspecific and may represent prior infarct, although can be further assessed on future follow-up studies.
