case_images: Two tumors were hypointense on T1-weighted image, isointense on T2-weighted image, and showed obvious and homogeneous enhancement on T1-weighted image contrast-enhanced scanning (Fig. 1). The tumors showed clear boundaries and signs of compression of the spinal cord.
case_images: Histologic description of ependymomas (World Health Organization grade II). (A) Perivascular pseudo-rosettes (hematoxylin and eosin, original magnification x 40). (B) Tumor cells were positive for glial fibrillary acidic protein staining (original magnification x 40). (C) Tumors were positive for S-100 protein (original magnification x 40). (D) The Ki-67 labeling index was <2% (original magnification x 40).

case_images: Combined with histological and immunohistochemical results, it is consistent with ependymoma (WHO grade II; Fig. 2).
case_images: Histologic description of meningioma (World Health Organization grade I). (A) syncytial growth of tumor cells with sparse psammoma bodies (hematoxylin and eosin, original magnification x 40). (B) Tumor cells were positive for epithelial membrane antigen staining (original magnification x 40). (C) Tumors were positive for progesterone receptor protein (original magnification x 40). (D) The Ki-67 labeling index was about 5% (original magnification x 40).
