Female, 59 years old, history of low-grade glioma, follow-up examination. Ill-defined thickening and T2 hyperintensity is again seen within the left temporal lobe showing no significant interval change. Gyriform susceptibility within the lesion likely correlates to calcification noted on prior CT. Vague smudgy enhancement is also seen within the lesion which appears less prominent than on prior studies. Sequelae of prior lesion biopsy are again demonstrated. 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 morphology.
1.Findings compatible with oligodendroglioma in the left temporal lobe are unchanged. No significant change in lesion size or signal characteristics is noted.2.A nonspecific subcentimeter focus of signal abnormality in the right cerebellum is unchanged as well.
