case_images: (A,B) Preoperative head MRI T1-weighted sequences and T2-weighted sequences demonstrating a rounded-like cystic solid lesion in the right frontoparietal lobe. (C-E) Axial, coronal, and parasagittal MRI in T1-weighted contrast-enhanced sequences showing the markedly enhanced margins and solid components of the lesion.

case_images: Contrast-enhanced scans revealed significant enhancement of the margins and solid components of the lesion (Figures 1A-E).
case_images: (A,B) Postoperative head MRI T1-weighted sequences and T2-weighted sequences illustrating complete resection of the cystic solid lesion in the right frontoparietal lobe. (C-E) Axial, coronal, and parasagittal MRI in T1-weighted contrast-enhanced sequences showing no significant enhancement in the surgical area.

case_images: Postoperative contrast-enhanced MRI showed gross total resection was achieved (Figures 2A-E).
case_images: Pathology and immunohistochemistry revealing glioblastoma with a small focal area of gliosarcoma. (A) H&E staining (100x) showed the tumor was mixed by glioma and sarcoma components. (B) Glial fibrillary acidic protein and (C) olig-2 was immunohistochemically positive in the tumor (100x). (D) Reticulin stains (100) disclosed abundant reticular fibers within tumor cells in the sarcomatous field.

case_images: The final pathology results confirmed a high-grade glioma with extensive necrosis (Figure 3A). Immunohistochemistry for glial fibrillary acidic protein (GFAP) and olig-2 was positive (Figures 3B,C), and reticulin stains revealed abundant reticular fibers within the tumor (Figure 3D).
