Nevertheless, they often present a diagnostic challenge because of the characteristic morphological features of a wide neck and shallow outpouching of the medial wall. The authors present the case of a 34-year-old woman who suffered a subarachnoid hemorrhage whose cause could not be determined on the initial imaging with digital subtraction (DS) angiography and CT angiography. Interestingly, MR imaging studies obtained on the 7th day revealed an intramural hematoma on the dorsal wall of the left internal carotid artery, which helped in the diagnosis of BBA on the third DS angiography study obtained on the 8th day, and in the surgical intervention on the 10th day. This case supports the hypothesis that focal dissection contributes to the formation of BBAs. Use of MR imaging in the subacute stage, in addition to DS and CT angiography, might be helpful in the diagnosis of BBAs.<\/jats:p>","DOI":"10.3171\/2011.8.jns11909","type":"journal-article","created":{"date-parts":[[2011,9,16]],"date-time":"2011-09-16T14:41:58Z","timestamp":1316184118000},"page":"1206-1209","source":"Crossref","is-referenced-by-count":40,"title":["Detection of blood blister\u2013like aneurysm and intramural hematoma with high-resolution magnetic resonance imaging"],"prefix":"10.3171","volume":"115","author":[{"given":"Nobutaka","family":"Horie","sequence":"first","affiliation":[{"name":"Departments of Neurosurgery and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Minoru","family":"Morikawa","sequence":"additional","affiliation":[{"name":"Radiology, Nagasaki University School of Medicine, Nagasaki, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shuji","family":"Fukuda","sequence":"additional","affiliation":[{"name":"Departments of Neurosurgery and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kentaro","family":"Hayashi","sequence":"additional","affiliation":[{"name":"Departments of Neurosurgery and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kazuhiko","family":"Suyama","sequence":"additional","affiliation":[{"name":"Departments of Neurosurgery and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Izumi","family":"Nagata","sequence":"additional","affiliation":[{"name":"Departments of Neurosurgery and"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"key":"b1-jns11909","series-title":"J Neurosurg","first-page":"419","article-title":"Blood blisterlike aneurysms of the internal carotid artery","volume":"89","author":"Abe","year":"1998"},{"key":"b2-jns11909","series-title":"Invest Radiol","first-page":"460","article-title":"High-resolution magnetic resonance imaging (MRI) at 3.0 Tesla in the short-term follow-up of patients with proven cervical artery dissection","volume":"42","author":"Bachmann","year":"2007"},{"key":"b3-jns11909","series-title":"J Clin Neurosci","first-page":"579","article-title":"Diagnostic accuracy and inter-rater reliability of 64-multislice 3D-CTA compared to intra-arterial DSA for intracranial aneurysms","volume":"17","author":"Franklin","year":"2010"},{"key":"b4-jns11909","series-title":"AJNR Am J Neuroradiol","first-page":"640","article-title":"Utility of CT angiography in the identification and characterization of supraclinoid internal carotid artery blister aneurysms","volume":"31","author":"Gaughen","year":"2010"},{"key":"b5-jns11909","series-title":"Neurosurgery","first-page":"403","article-title":"Pathological consideration of a \u201cblister-like\u201d aneurysm at the superior wall of the internal carotid artery: case report","volume":"40","author":"Ishikawa","year":"1997"},{"key":"b6-jns11909","series-title":"J Neurosurg","first-page":"781","article-title":"Acute extracranial-intracranial bypass using a radial artery graft along with trapping of a ruptured blood blister\u2013like aneurysm of the internal carotid artery.
