We describe the case of a patient who presented with an unruptured aneurysm associated with a double origin of the posterior inferior cerebellar artery (DOPICA), a rare variant of aberrant origin. A three-dimensional rotational angiogram clearly showed that the aneurysm incorporated the origin of the DOPICA caudal channel, which was more dominant than the cranial one. The aneurysm was completely obliterated using detachable coils after a balloon occlusion test (BOT) of the caudal channel was conducted to confirm the tolerance of the patient following sudden interruption of the more prominent flow coming from the caudal channel of the DOPICA. This report affirms the need to suspect anomalies associated with a DOPICA that predispose to intracranial aneurysms and highlights the potential role of a BOT in pretreatment hemodynamic evaluations of unusual aneurysms accompanying a particular developmental anomaly.<\/jats:p>","DOI":"10.1177\/159101991101700207","type":"journal-article","created":{"date-parts":[[2017,1,11]],"date-time":"2017-01-11T09:10:34Z","timestamp":1484125834000},"page":"183-187","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":11,"title":["Successful Endosaccular Coiling after a Balloon Occlusion Test of the Caudal Channel of a Double Origin of the Posterior Inferior Cerebellar Artery Originating from the Aneurysm Neck"],"prefix":"10.1177","volume":"17","author":[{"given":"S.H.","family":"Lee","sequence":"first","affiliation":[{"name":"Stroke and Neurological Disorders Centre, Kyung Hee University Hospital at Gangdong; Seoul, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J.S.","family":"Koh","sequence":"additional","affiliation":[{"name":"Stroke and Neurological Disorders Centre, Kyung Hee University Hospital at Gangdong; Seoul, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"C.W.","family":"Ryu","sequence":"additional","affiliation":[{"name":"Stroke and Neurological Disorders Centre, Kyung Hee University Hospital at Gangdong; Seoul, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"C.Y.","family":"Lee","sequence":"additional","affiliation":[{"name":"Stroke and Neurological Disorders Centre, Kyung Hee University Hospital at Gangdong; Seoul, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"S.J.","family":"Lee","sequence":"additional","affiliation":[{"name":"Stroke and Neurological Disorders Centre, Kyung Hee University Hospital at Gangdong; Seoul, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2011,6,1]]},"reference":[{"issue":"5","key":"bibr1-159101991101700207","first-page":"242","volume":"61","author":"Kwon BJ","year":"2007","journal-title":"Neurosurgery"},{"key":"bibr2-159101991101700207","doi-asserted-by":"publisher","DOI":"10.3171\/jns.1985.63.2.0235"},{"key":"bibr3-159101991101700207","doi-asserted-by":"publisher","DOI":"10.1007\/s12311-009-0108-6"},{"key":"bibr4-159101991101700207","first-page":"425","volume":"25","author":"Lesley WS","year":"2004","journal-title":"Am J Neuroradiol"},{"key":"bibr5-159101991101700207","doi-asserted-by":"publisher","DOI":"10.2214\/AJR.07.2453"},{"key":"bibr6-159101991101700207","doi-asserted-by":"publisher","DOI":"10.3171\/jns.2002.96.1.0127"},{"key":"bibr7-159101991101700207","doi-asserted-by":"publisher","DOI":"10.1227\/01.neu.0000303206.92617.07"}],"container-title":["Interventional Neuroradiology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/159101991101700207","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/159101991101700207","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,29]],"date-time":"2026-04-29T10:54:47Z","timestamp":1777460087000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/159101991101700207"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2011,6]]},"references-count":7,"journal-issue":{"issue":"2","published-print":{"date-parts":[[2011,6]]}},"alternative-id":["10.1177\/159101991101700207"],"URL":"https:\/\/doi.org\/10.1177\/159101991101700207","relation":{},"ISSN":["1591-0199","2385-2011"],"issn-type":[{"value":"1591-0199","type":"print"},{"value":"2385-2011","type":"electronic"}],"subject":[],"published":{"date-parts":[[2011,6]]}}}
