The cause of this benign form of SAH remains unknown. The authors report on two cases of perimesencephalic nonaneurysmal SAH in which a small bulge on the basilar artery (BA) was demonstrated on three-dimensional rotational angiography studies. Based on data from these cases, one may infer that the lesion on the BA is responsible for the SAH. The possible pathogenesis is discussed.<\/jats:p>","DOI":"10.3171\/jns.2003.98.2.0426","type":"journal-article","created":{"date-parts":[[2009,5,13]],"date-time":"2009-05-13T17:55:36Z","timestamp":1242237336000},"page":"426-429","source":"Crossref","is-referenced-by-count":22,"title":["Significance of a small bulge on the basilar artery in patients with perimesencephalic nonaneurysmal subarachnoid hemorrhage"],"prefix":"10.3171","volume":"98","author":[{"given":"Yuji","family":"Matsumaru","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kiyoyuki","family":"Yanaka","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ai","family":"Muroi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hiroaki","family":"Sato","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takao","family":"Kamezaki","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tadao","family":"Nose","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1754","reference":[{"key":"b1","series-title":"J Neurosurg","doi-asserted-by":"publisher","first-page":"537","DOI":"10.3171\/jns.1986.64.4.0537","article-title":"Spontaneous subarachnoid hemorrhage and negative cerebral panangiography.
