One patient died shortly after surgical exploration and the other after ventriculography. The pathophysiology of hydrocephalus associated with a vascular malformation is discussed and the need for considering a benign cause for obstructive hydrocephalus from a mass deep in the brain substance is emphasized.<\/jats:p>","DOI":"10.3171\/jns.1971.34.2part1.0229","type":"journal-article","created":{"date-parts":[[2009,5,7]],"date-time":"2009-05-07T14:38:28Z","timestamp":1241707108000},"page":"229-235","source":"Crossref","is-referenced-by-count":6,"title":["Hematoma from arteriovenous malformation producing hydrocephalus and simulating a thalamic tumor"],"prefix":"10.3171","volume":"34","author":[{"given":"Larry K.
