case_images: Cranial CT and MRI images before tumor resection. (A). On admission, cranial CT showed a right frontal cystic lesion with fluid level. Cystic fluid was observed above blood. (B, C). Axial and sagittal cranial CT images showed that the drainage tube was in the cyst, avoiding the solid component of the tumor after right frontal sac puncture. (D, E). Axial and coronal cranial MRI images indicated that after the right frontal sac puncture, the sac fluid was discharged, and the solid component of the tumor was visible. The diagnosis was considered to be glioma.

case_images: Additionally, no evidence of fresh hemorrhage was observed ( Figures 1B, C ). Cranial magnetic resonance imaging (MRI) revealed a glioma in the right frontal region ( Figures 1D, E ).

case_images: During the surgical procedure, a frontal coronal flap was utilized to create a bone window measuring approximately 5x6 cm ( Figures 2A, B ).

case_images: Postoperative head MRI findings. (A) Postoperative axial cranial MRI indicated that the tumor was completely removed. (B) Postoperative coronal cranial MRI indicated that the tumor was completely removed, the midline was in the center, and ventricular compression was relieved.

case_images: Reevaluation of the cerebral magnetic resonance imaging (MRI) revealed that the tumor was completely resected ( Figures 3A, B ).
case_images: The result of pathological assessments. H&E staining showed that the density of tumor cells increased, the cells were round or oval, and perinuclear halos and nucleoli were visible. Local microvascular hyperplasia of the tumor. The pathological results indicated that the tumor was oligodendroglioma (WHO grade III). Scale bar: 200 mum.
