MRI and CT findings. Preoperative MRI revealed an irregular hyperintense mass in sagittal T1 (A) and hypointensity in T2 (B). The lesion was solid with hemorrhage in sagittal (C) and coronal (E) imaging after administration of gadolinium and was intramedullary on axial enhanced MRI (F). Postoperative contrast-enhanced MRI showed the tumor was totally resected (D). Preoperative CT depicted high calcification the hyperdense mass (G, H). Red arrow: location of the tumor
