Figure 1: (A) Initial T2W axial MRI showing 4th ventricle ependymoma. (B) Postoperative CT scan with no residual lesion. (C–F) Preoperative MRI showing T1W isointense lesion with significant midline shift (black arrow), no recurrence in posterior fossa (blue arrow) and perilesional edema on T2W sequence. Contrast images show dural-based enhancing lesion with bony and galeal involvement (green arrow). Orange arrow in 1F is to indicate heterogenous hyperintense lesion with perilesional edema on T2W sequence. (G, H) Intraoperative photographs revealing bony involvement and dural-based yellowish-white hard tumor. Black arrow in 1G indicates bony involvement while 1H indicates dural-based lesion. (I) Postoperative CT scan showing complete excision
