case_images: An MRI 3-Tesla scan of the brain demonstrated a solid, well-demarcated homogeneous mass which may have a dural attachment (Figure 1). The choline monopeak in the tumor corresponds to an extra-axial tumor, and the lack of resonance in the lipid area confirms the diagnosis of an extra-axial tumor and also excludes a metastasis (Figure 1).
case_images: A patternless, highly cellular lesion is seen with increased mitotic activity (H&E, x200, original magnification).
