    Surgical treatment for posttraumatic hemorrhage inside a filum terminale myxopapillary ependymoma: a case report and literature review

    Symptoms of cauda equina syndrome due to ependymoma in the conus medullaris or filum terminale develop slowly. However, hemorrhagic change inside spinal tumors can induce acute neurologic decline. Here, we rep...
