Similarities to five previously reported cases are discussed, with emphasis on the mode of metastasis. Factors most closely associated with distant metastases include early onset, numerous local operations, long survival, and massive local recurrence at the time of distant metastases.<\/jats:p>","DOI":"10.3171\/jns.1977.47.5.0771","type":"journal-article","created":{"date-parts":[[2009,5,7]],"date-time":"2009-05-07T15:15:37Z","timestamp":1241709337000},"page":"771-775","source":"Crossref","is-referenced-by-count":37,"title":["A metastasizing ependymoma of the cauda equina"],"prefix":"10.3171","volume":"47","author":[{"given":"Constantine","family":"Mavroudis","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jeannette J.","family":"Townsend","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Charles B.","family":"Wilson","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1754","reference":[{"key":"b1","series-title":"J Neurosurg","doi-asserted-by":"publisher","first-page":"88","DOI":"10.3171\/jns.1970.33.1.0088","article-title":"Glioblastoma multiforme with extracranial metastases in the absence of previous craniotomy.
