Abstract
Although involvement of other regions of the spinal cord and brain stem is seen, myxopapillary ependymoma is most commonly found at the filum terminal e or cauda equina. Less commonly, myxopapillary ependymoma may occur outsid e the central nervous system from direct metastatic extension of an intrath ecal tumor, and rarely it may present as a primary tumor outside the thecal sac. The authors present a case of primary sacral myxopapillary ependymoma , which was first diagnosed as a chordoma. They then discuss the magnetic r esonance imaging findings of this and other sacral tumors. Myxopapillary ep endymoma should be considered in the differential diagnosis for a primary e xpansile sacral mass along with other lesions such as chordoma, aneurysmal bone cyst, and giant cell tumor.
