Figure 1. MRI images in coronal (a), sagittal (b) and axial plane (c) demonstrating the area of the tumor where the voxel of the performed MRS study (d) was obtained.
Figure 2.
Figure 2. 1H-MRS of the tumor area (left) showing the high Chol/NAA ratio in comparison to the normal MRS findings of the opposed normal brain tissue (right).
Figure 3.
Figure 3. Axial images of the performed brain SPECT with technetium-99m (Tc99m) demonstrating high standardized uptake value (SUV).
Figure 4.
Figure 4. The tumor cells form lobules some partly demarcated by thin collagenous septae (hematoxylin and eosin stain, original magnification × 10).
Figure 5.
Figure 5. The tumor cells are uniform with oval nuclei with delicate chromatin that on occasion show central clearing or the formation of nuclear inclusions. Psammoma bodies are present (hematoxylin and eosin stain, original magnification × 40).
