During a normal postoperative course, computerized tomography (CT) scanning demonstrated a spherically hyperdense structure near the internal carotid artery, enlarging on a control CT scan. A suspected false aneurysm was confirmed on magnetic resonance imaging; angiographic studies were negative. The authors believed they were dealing with a thrombosed false aneurysm and they performed operative revision. Intraoperatively the \u201caneurysm\u201d could be dissected off the internal carotid artery and no lesion of the arterial wall was obvious. Histological findings showed a fresh blood clot. This case demonstrates that a blood clot may mimic an aneurysm on CT and magnetic resonance studies, which has not been described earlier. The origin of the blood clot remains unclear.<\/jats:p>","DOI":"10.3171\/jns.1999.91.4.0679","type":"journal-article","created":{"date-parts":[[2009,5,13]],"date-time":"2009-05-13T17:22:50Z","timestamp":1242235370000},"page":"679-681","source":"Crossref","is-referenced-by-count":0,"title":["Growing blood clot mimicking an aneurysm on postoperative computerized tomography and magnetic resonance imaging studies"],"prefix":"10.3171","volume":"91","author":[{"given":"Alexander","family":"Bertalanffy","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wolfgang","family":"Dietrich","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Martin","family":"Aichholzer","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Karl","family":"Hittmair","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Thomas","family":"Czech","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1754","reference":[{"key":"b1","series-title":"Neurosurgery","first-page":"774","article-title":"Carotid cavernous fistula and false aneurysm of the cavernous carotid artery: complications of transsphenoidal surgery.","volume":"31","author":"Ahuja","year":"1992"},{"key":"b2","series-title":"Neurol Res","doi-asserted-by":"publisher","first-page":"135","DOI":"10.1080\/01616412.1996.11740391","article-title":"A false traumatic giant aneurysm of the supraclinoid carotid artery.
