Images obtained from the preoperative cranial MRI: the right frontal lobe space-occupying lesions. (A) axial T1 enhanced, (B) Sagittal T1 enhanced, and (C) Coronal T1 enhanced. (D,E) Emergency cranial CT during the operation: found the low-density of the epidural behind the surgical area. (orange arrow). (F) Photo of the epidural during decompressive craniectomy: gelatinous substance in the epidural area.

Magnetic resonance imaging (MRI) of the head showed a space-occupying lesions in the right frontal lobe (Figures 1A-C). An emergency CT scan showed a low-density, spindle-shaped epidural lesions (Figures 1D,E). A large amount of colorless and transparent gelatinous substances were found in the epidural area of the patient (Figure 1F). Pathological examination showed H&E staining of a pleomorphic glial tumor with round tumor cells and high mitotic activity (Figure 1G). The right frontal lesions was graded as anaplastic oligodendroglioma, IDH mutated, 1p/19q codeleted, WHO III (Figures 1G,H).
