The authors report on a 42-year-old man who initially sought treatment for a ruptured saccular aneurysm of the right middle cerebral artery, which was successfully eliminated by surgical clipping of the aneurysm neck. Two years later, the patient presented with another subarachnoid hemorrhage and was found to have a dissecting aneurysm of the right vertebral artery, which arose from a previously angiographically documented normal artery. This rare association sheds light on the causes and growth of two distinct types of aneurysms, both clinically and pathologically.<\/jats:p>","DOI":"10.3171\/jns.2002.97.3.0701","type":"journal-article","created":{"date-parts":[[2009,5,13]],"date-time":"2009-05-13T17:44:05Z","timestamp":1242236645000},"page":"701-704","source":"Crossref","is-referenced-by-count":6,"title":["De novo dissecting aneurysm in a patient with a ruptured saccular lesion"],"prefix":"10.3171","volume":"97","author":[{"given":"Toshiki","family":"Ikeda","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hiroki","family":"Kurita","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yoshifumi","family":"Konishi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mitsuyuki","family":"Fujitsuka","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ken","family":"Hino","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yoshiaki","family":"Shiokawa","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Isamu","family":"Saito","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1754","reference":[{"key":"b1","series-title":"Neurology","doi-asserted-by":"publisher","first-page":"868","DOI":"10.1212\/WNL.38.6.868","article-title":"Dissection of the intracranial vertebral artery.","volume":"38","author":"Caplan","year":"1988"},{"key":"b2","series-title":"Neurosurgery","doi-asserted-by":"publisher","first-page":"88","DOI":"10.1227\/00006123-198901000-00014","article-title":"De novo aneurysm formation following carotid ligation: case report and review of the literature.","volume":"24","author":"Dyste","year":"1989"},{"key":"b3","series-title":"Neurosurgery","first-page":"732","article-title":"A pathological study of intracranial posterior circulation dissecting aneurysms with subarachnoid hemorrhage: report of three autopsied cases and review of the literature.","volume":"33","author":"Endo","year":"1993"},{"key":"b4","series-title":"J Neurosurg","doi-asserted-by":"publisher","first-page":"325","DOI":"10.3171\/jns.1984.60.2.0325","article-title":"Subarachnoid hemorrhage from intracranial dissecting aneurysm.","volume":"60","author":"Friedman","year":"1984"},{"key":"b5","series-title":"Acta Neurochir","doi-asserted-by":"publisher","first-page":"20","DOI":"10.1007\/BF02001464","article-title":"De novo aneurysm formation and aneurysm growth following therapeutic carotid occlusion for intracranial internal carotid artery (ICA) aneurysms.","volume":"120","author":"Fujiwara","year":"1993"},{"key":"b6","series-title":"J Neurol Neurosurg Psychiatry","doi-asserted-by":"publisher","first-page":"153","DOI":"10.1136\/jnnp.27.2.153","article-title":"Report of a case of cerebral aneurysm in an adult developing apparently de novo.","volume":"27","author":"Graf","year":"1964"},{"key":"b7","series-title":"Neurology","doi-asserted-by":"publisher","first-page":"1163","DOI":"10.1212\/WNL.50.4.1163","article-title":"Rapid development of giant fusiform cerebral aneurysms in angiographically normal vessels.","volume":"50","author":"Johnston","year":"1998"},{"key":"b8","series-title":"Stroke","doi-asserted-by":"publisher","first-page":"485","DOI":"10.1161\/01.STR.32.2.485","article-title":"Factors affecting formation and growth of intracranial aneurysms: a long-term follow-up study.","volume":"32","author":"Juvela","year":"2001"},{"key":"b9","series-title":"Neurosurg Rev","doi-asserted-by":"publisher","first-page":"177","DOI":"10.1007\/BF02389328","article-title":"Development of a dissecting aneurysm on the vertebral artery immediately after occlusion of the contralateral vertebral artery: a case report.","volume":"21","author":"Kubo","year":"1998"},{"key":"b10","series-title":"Neurosurgery","doi-asserted-by":"publisher","first-page":"871","DOI":"10.1097\/00006123-199904000-00110","article-title":"De novo formation of familial cerebral aneurysms: case report.","volume":"44","author":"Lebland","year":"1999"},{"key":"b11","series-title":"Clin Neurol Neurosurg","doi-asserted-by":"publisher","first-page":"233","DOI":"10.1016\/0303-8467(95)00035-I","article-title":"\u2018De novo\u2019 aneurysm formation: report of two cases.","volume":"97","author":"Maiuri","year":"1995"},{"key":"b12","series-title":"Surg Neurol","doi-asserted-by":"publisher","first-page":"173","DOI":"10.1016\/0090-3019(85)90181-8","article-title":"\u201cDe novo\u201d aneurysms.
