Some investigators believe that such dilatations are in fact aneurysmal. This paper reports and assesses the gross and histological findings in seven junctional dilatations discovered at autopsy, including one aneurysm mistakenly diagnosed angiographically. There were no significant histological abnormalities in any case. It is concluded that a junctional dilatation is neither aneurysmal nor preaneurysmal and is probably not even a pathological entity.<\/jats:p>","DOI":"10.3171\/jns.1970.33.5.0529","type":"journal-article","created":{"date-parts":[[2009,5,7]],"date-time":"2009-05-07T14:29:05Z","timestamp":1241706545000},"page":"529-531","source":"Crossref","is-referenced-by-count":55,"title":["The clinical significance of junctional dilatation of the posterior communicating artery"],"prefix":"10.3171","volume":"33","author":[{"given":"Fred","family":"Epstein","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joseph","family":"Ransohoff","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gleb N.","family":"Budzilovich","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"key":"b1","series-title":"J.
