Figure 3

Thirty-one-year-old female, presenting with epileptic seizure. MRI showed a non-enhancing lesion in the left frontal operculum. On PET/CT the tumor was photopenic (SUVmax: 1.5 vs. 1.8, TBRmax: 0.8). Due to misinterpretation, the lesion was handled as low grade. First, a follow-up MRI made after 120 days already showed slight enhancement in the cranial part of the tumor. After waking surgical removal, histology revealed grade 4 astrocytoma with IDH mutation and a Ki-67 proliferation rate of 15%.
