Double myxopapillary ependymomas of the filum terminale.

intradural tumors (WHO grade I) that characteristically occur in the conus medullaris/filum terminale region. They are slow growing tumors with a good prognosis and long-term survival.1 We report a rare case of double MPE occurring at both extremities of the filum terminale. In the light of the present case and an extensive review of the literature, we summarize the imaging characteristics and intra-operative findings that should be present when considering the diagnosis of double MPE. Knowledge of this entity should remind recall physicians to assess in detail the entire region of the conus medullaris/filum terminale to prevent missing the diagnosis of a second MPE. This is important since the surgical treatment should address both lesions.
