  1. Ueki K, Sasaki T, Ishida T, Kirino T. Spinal tanycytic ependymoma associated with neurofibromatosis type 2--case report. Neurol Med Chir (Tokyo). 2001;41:513-6 pubmed
    ..These findings were compatible with the diagnosis of tanycytic ependymoma. This rare subtype of ependymoma appears to arise through inactivation of NF2, in addition to some typical ependymomas. ..
  2. Arai T, Tani S, Isoshima A, Nagashima H, Joki T, Takahashi Fujigasaki J, et al. [Intraoperative photodynamic diagnosis for spinal ependymoma using 5-aminolevulinic acid: technical note]. No Shinkei Geka. 2006;34:811-7 pubmed
    ..5-ALA-induced porphyrin fluorescence may label spinal ependymomas easily and clearly enough to enhance the completeness of tumor removal. ..
  3. Nakamura M, Ishii K, Watanabe K, Tsuji T, Takaishi H, Matsumoto M, et al. Surgical treatment of intramedullary spinal cord tumors: prognosis and complications. Spinal Cord. 2008;46:282-6 pubmed
    ..Predictors of good surgical outcome for intramedullary spinal cord tumors were histological grades of the tumors, surgical margins, and neurological status of the patient before surgery. ..
  4. Nakamura M, Ishii K, Watanabe K, Tsuji T, Matsumoto M, Toyama Y, et al. Long-term surgical outcomes for myxopapillary ependymomas of the cauda equina. Spine (Phila Pa 1976). 2009;34:E756-60 pubmed publisher
    ..Therefore, early diagnosis is essential, and a therapeutic strategy including radiotherapy, on the assumption that this tumor is malignant, should be established. ..
  5. Ishihama H, Nakamura M, Funao H, Ishii K, Matsumoto M, Toyama Y, et al. A rare case of spinal dumbbell tanycytic ependymoma. Spine (Phila Pa 1976). 2011;36:E612-4 pubmed publisher
    ..A rare case of spinal dumbbell-type tanycyticependy-moma was presented. Detailed histologic examinations are essential to differentiate tanycyticependymoma from other tumors such as schwannoma and pilocyticastrocytoma. ..
  6. Murai T, Sato K, Iwabuchi M, Manabe Y, Ogino H, Iwata H, et al. Re-irradiation of recurrent anaplastic ependymoma using radiosurgery or fractionated stereotactic radiotherapy. Jpn J Radiol. 2016;34:211-8 pubmed publisher
    ..Because local recurrence of tumors may result in patient death, a minimum dose of 21 Gy/3 fr or 25 Gy/5 fr or higher may be most suitable for treatment of these cases. ..
  7. Shibahara J, Kashima T, Kikuchi Y, Kunita A, Fukayama M. Podoplanin is expressed in subsets of tumors of the central nervous system. Virchows Arch. 2006;448:493-9 pubmed
    ..Given the widespread expression of podoplanin, the antibody D2-40 is of little use in diagnostic practice for CNS tumors. ..
  8. Aizawa T, Hasegawa K, Ohkumo T, Haga S, Ikeda K, Yoshikawa K. Neural stem cell-like gene expression in a mouse ependymoma cell line transformed by human BK polyomavirus. Cancer Sci. 2011;102:122-9 pubmed publisher
    ..These results suggest that this murine ependymoma cell line recapitulates the gene expression profile in ependymal cells undergoing malignant transformation...
