Patients with fast-growing aortic aneurysms show a high incidence of rupture. Gram-positive organisms, such as the <jats:italic>Staphylococ<\/jats:italic>cus and <jats:italic>Enterococcus<\/jats:italic> species, are the most common cause of infection.<\/jats:p>\n<\/jats:sec>\n<jats:sec>\n<jats:title>Case presentation<\/jats:title>\n<jats:p>A 91-year-old man presented at our facility with high grade fever and tachypnea, which he had experienced for the previous two days. He had a history of end-stage renal disease and had been undergoing regular chest computed tomography (CT) follow-up for a left lower lung nodule. CT imaging with intravenous contrast media showed a thoracic aortic aneurysm with hemothorax. Rupture of the aneurysm was suspected. CT imaging performed a year ago showed a normal aorta. Blood samples showed a <jats:italic>Bacillus cereus<\/jats:italic> infection. The patient was successfully treated for a mycotic aortic aneurysm secondary to <jats:italic>Bacillus cereus<\/jats:italic> bacteremia.<\/jats:p>\n<\/jats:sec>\n<jats:sec>\n<jats:title>Conclusions<\/jats:title>\n<jats:p>Here, we report a rare of an infected aneurysm of the thoracic aorta probably caused by <jats:italic>Bacillus cereus<\/jats:italic>. Although infected aneurysms have been described well before, an aneurysm infected with <jats:italic>Bacillus cereus<\/jats:italic> is rare. <jats:italic>Bacillus cereus<\/jats:italic>, a gram-positive spore-building bacterium, can produce biofilms, which attach to catheters. It has recently emerged as a new organism that can cause serious infection.<\/jats:p>\n<\/jats:sec>","DOI":"10.1186\/s12879-019-4602-2","type":"journal-article","created":{"date-parts":[[2019,11,11]],"date-time":"2019-11-11T13:03:23Z","timestamp":1573477403000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Infected aneurysm of the thoracic aorta probably caused by Bacillus cereus: a case report"],"prefix":"10.1186","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6631-1632","authenticated-orcid":false,"given":"Tzu-Chi","family":"Wu","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ching-Chou","family":"Pai","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pin-Wen","family":"Huang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chun-Bin","family":"Tung","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2019,11,11]]},"reference":[{"key":"4602_CR1","doi-asserted-by":"publisher","first-page":"43","DOI":"10.1186\/s12941-015-0104-2","volume":"14","author":"M Ikeda","year":"2015","unstructured":"Ikeda M, Yagihara Y, Tatsuno K, Okazaki M, Okugawa S, Morita K.
