The present report describes a 21-year-old woman with recurrent SAH and TA. In addition, she also had recurrent spells of postural weakness in the bilateral lower limb occurring at the same time. Sequential CT of the head and MRI showed bilateral cortical SAH. Vascular imaging with MR angiogram and CT angiogram showed bilateral subclavian arteries and left common carotid artery occlusion with multiple hypertrophied collaterals vessels in the neck. There was no evidence of aneurysms in the intracranial vasculature in the conventional angiogram. The CT angiogram of the aorta showed severe stenosis of the abdominal aorta above the renal arteries. The patient was treated with immunomodulatory therapy and had a favourable outcome without further recurrence at end of 1\u2005year of follow-up. A review of the literature showed 21cases with aneurysmal SAH and three cases non-aneurysmal SAH in patients with TA have been reported. Various factors are responsible for the reorganisation of the intracranial of the arteries in patients with chronic vasculitis in the presence of extracranial stenosis and occlusion, which could possibly explain the SAH in absence of aneurysm in patients with TA.<\/jats:p>","DOI":"10.1136\/bcr-2013-008825","type":"journal-article","created":{"date-parts":[[2013,6,14]],"date-time":"2013-06-14T03:12:21Z","timestamp":1371179541000},"page":"bcr2013008825","source":"Crossref","is-referenced-by-count":9,"title":["Recurrent non-aneurysmal subarachnoid haemorrhage in Takayasu arteritis: is the cause immunological or mechanical?"],"prefix":"10.1136","volume":"2013","author":[{"given":"Umar Ashfaq","family":"Shuaib","sequence":"first","affiliation":[{"name":"Shifa College of Medicine, Islamabad, Pakistan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mahesh","family":"Kate","sequence":"additional","affiliation":[{"name":"Department of Medicine, University of Alberta, Edmonton, Alberta, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joanne","family":"Homik","sequence":"additional","affiliation":[{"name":"Department of Medicine, University of Alberta, Edmonton, Alberta, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thomas","family":"Jerrakathil","sequence":"additional","affiliation":[{"name":"Department of Medicine, University of Alberta, Edmonton, Alberta, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2013,6,13]]},"reference":[{"key":"2025082722372870000_2013.jun13_1.bcr2013008825.1","doi-asserted-by":"crossref","first-page":"481","DOI":"10.1136\/jcp.55.7.481","article-title":"Takayasu arteritis: a review","volume":"2013","author":"Johnston","year":"2002","journal-title":"J Clin Pathol"},{"key":"2025082722372870000_2013.jun13_1.bcr2013008825.2","doi-asserted-by":"crossref","first-page":"284","DOI":"10.1080\/03009740510026526","article-title":"Clinical characteristics and outcomes of Takayasu's arteritis: analysis of 108 patients using standardized criteria for diagnosis, activity assessment and angiographic classification","volume":"2013","author":"Park","year":"2005","journal-title":"Scand J Rheumatol"},{"key":"2025082722372870000_2013.jun13_1.bcr2013008825.3","doi-asserted-by":"crossref","first-page":"33","DOI":"10.1007\/s11604-007-0184-9","article-title":"Multiple cerebral aneurysms associated with Takayasu arteritis successfully treated with coil embolization","volume":"2013","author":"Takayama","year":"2008","journal-title":"Radiat Med"},{"key":"2025082722372870000_2013.jun13_1.bcr2013008825.4","doi-asserted-by":"crossref","first-page":"695","DOI":"10.3346\/jkms.2002.17.5.695","article-title":"Takayasu's arteritis presented with subarachnoid hemorrhage: report of two cases","volume":"2013","author":"Kim","year":"2002","journal-title":"J Korean Med Sci"},{"key":"2025082722372870000_2013.jun13_1.bcr2013008825.5","doi-asserted-by":"crossref","first-page":"119","DOI":"10.2176\/nmc.51.119","article-title":"Takayasu's arteritis complicated with subarachnoid hemorrhage and hematomyelia","volume":"2013","author":"Hyun","year":"2011","journal-title":"Neurol Med Chir (Tokyo)"},{"key":"2025082722372870000_2013.jun13_1.bcr2013008825.6","doi-asserted-by":"crossref","first-page":"139","DOI":"10.1159\/000018348","article-title":"Takayasu arteritis and cutaneous necrotizing vasculitis","volume":"2013","author":"Skaria","year":"2000","journal-title":"Dermatology"},{"key":"2025082722372870000_2013.jun13_1.bcr2013008825.7","first-page":"169","article-title":"Nonpulsatile cerebral perfusion in Takayasu's arteritis","volume":"2013","author":"Lee","year":"2003","journal-title":"J Neuroimaging"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2013-008825","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,28]],"date-time":"2025-08-28T05:37:41Z","timestamp":1756359461000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2013-008825"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2013,6,13]]},"references-count":7,"alternative-id":["10.1136\/bcr-2013-008825"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2013-008825","relation":{},"ISSN":["1757-790X"],"issn-type":[{"value":"1757-790X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2013,6,13]]}}}
