Both had severe back pain at the onset. One patient had a subdural hematoma that compressed the conus medullaris and cauda equina, and was drained percutaneously; the other had clots in the subarachnoid space. The cerebrospinal fluid showed a polymorphonuclear pleocytosis that simulated septic meningitis. Complete spinal angiography failed to reveal a cause for the hemorrhages.<\/jats:p>","DOI":"10.3171\/jns.1984.61.5.0975","type":"journal-article","created":{"date-parts":[[2009,5,8]],"date-time":"2009-05-08T16:20:37Z","timestamp":1241799637000},"page":"975-980","source":"Crossref","is-referenced-by-count":53,"title":["Spontaneous spinal subarachnoid hemorrhage and subdural hematoma"],"prefix":"10.3171","volume":"61","author":[{"given":"Karl W.","family":"Swann","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Allan H.","family":"Ropper","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Paul F.
