case_images: Plain CT demonstrated a hyperdense lesion with multiple calcifications and proliferating adjacent blood vessels in the left parietal lobe. (A) T1-weighted MRI showed hypointense irregular abnormal cortical and subcortical regions. (B) T2-weighted MRI demonstrated a hyperintense mass. (C) MR post gadolinium enhancement showed enhanced pia mater and cortex. (D) Magnetic resonance spectroscopy (MRS) revealed decreased NAA and increased Cho in the lesion. The Cho/Cr ratio was markedly elevated (3.94), while the NAA/Cr ratio was reduced (0.43) in the lesion area (E).

case_images: No personal or family history of neurological diseases was reported, but plain computed tomography (CT) demonstrated a hyperdense lesion with multiple calcifications and proliferating adjacent blood vessels in the left parietal lobe (Figure 1A). MRI demonstrated a hyperintense mass (Figure 1C). MR post gadolinium enhancement showed enhanced pia mater and cortex (Figure 1D). Furthermore, MRS revealed decreased NAA and increased Cho in the lesion (Figure 1E).
case_images: Surgical microscopic examination showed an ill-defined mass with a grayish-yellow surface. The overlying dura was involved (black arrow) and the surrounding tissue was slightly edematous (A,B). Biopsy showed a diffused proliferation of spindle and oval cells with some psammoma bodies present in the cortex (C,D).

case_images: The overlying dura was determined to be involved, and the surrounding tissues were slightly edematous (Figures 2A,B). Extensive spindle-shaped cells were found to be arranged in a whorled pattern surrounding the vessels, and syncytial cells were present in local regions (Figures 2C,D).
