“…The most common clinical features consisted of fever, abdominal pain, and/or back pain, the last of which may be related to the site of involvement (131). A computed tomographic (CT) scan with contrast enhancement is considered the method of choice to diagnose mycotic aneurysm because of its ability to detect early changes in the arterial wall and the periaortic tissue (63,131). These changes include a periaortic soft tissue density with rim enhancement (Fig.…”

“…These changes include a periaortic soft tissue density with rim enhancement (Fig. 1), an eccentric, thickened wall with rapid growth, lack of calcium in the aneurysmal wall of the aorta, and gas in the perianeurysmal soft tissue (63). Angiography may subsequently be performed for confirmation of the diagnosis or assistance in planning future surgical procedures.…”

“…Mycotic aneurysm caused by Salmonella was almost uniformly fatal in previous times; however, multiple publications of case reports and case series found that early surgical intervention has greatly increased survival (3,27,63,105,131,142,150). Most surgeons consider the excision of an infected vessel with extra-anatomic vascular reconstruction to be the surgery of choice for abdominal mycotic aneurysm (142).…”

SUMMARY Nontyphoid Salmonella strains are important causes of reportable food-borne infection. Among more than 2,000 serotypes, Salmonella enterica serotype Choleraesuis shows the highest predilection to cause systemic infections in humans. The most feared complication of serotype Cholearesuis bacteremia in adults is the development of mycotic aneurysm, which previously was almost uniformally fatal. The advances in diagnostic techniques, surgical care, and antimicrobial therapy have greatly improved the survival of these patients. However, the recent emergence of serotype Choleraesuis that is resistant to ampicillin, chloramphenicol, trimethoprim-sulfamethoxazole, and, notably, fluoroquinolone antibiotics has aroused concern about the use of these agents for the empirical treatment of systemic infection caused by this organism. In view of the serious implications of the situation, the chain of transmission and mechanism of resistance should be carefully studied to reduce the spread of infection and threat to human health. To date, there are no vaccines available to prevent serotype Choleraesuis infections in humans. The availability, in the near future, of the genome sequence of serotype Cholearesuis will facilitate the development of effective vaccines as well as the discovery of new targets for novel antimicrobial agents.

“…In earlier angiographic studies, infected aneurysms did no have specific features that distinguish them from atherosclerotic aneurysms except for sudden appearance, rapid progression or uncommon location (6,7). Indeed, the infra-renal aorta is a typical localization but combined involvement of other parts of the aorta (thoracic, thoraco-abdominal and supra-renal) account for the majority of cases.…”

Infectious aneurysms are almost invariably of bacterial origin. It is a rare life-threatening disease, with a mortality reaching 67% in the absence of an early treatment (1), due to hemorrhage and uncontrolled sepsis.Clinical and biological findings are not specific and the diagnostic is often delayed. In the presence of fever and sepsis, CT is the imaging method of choice as several features may indicate the infectious origin and distinguish from atherosclerotic aneurysms. Case reportA 55-year-old woman was admitted in our institution because of fever and abdominal pain.Upon admission, she presented with tachycardia (110 bpm) and slightly decreased blood pressure (110/70 mmHg). Infection of the lower urinary tract was suspected at first. Blood tests showed an important inflammatory syndrome with increased C-reactive protein (CRP) levels (34 mg/dL, normal: < 1 mg/dL). However, urine analysis did not disclose any abnormal findings. A CT-scan of the whole abdomen was performed (Fig. 1).CT revealed an important infiltration of the retroperitoneal fat surrounding the distal part of the abdominal aorta as well as the proximal portion of the right iliac artery. The density of the infiltrated fat was evaluated at 20 HU, which was hardly compatible with blood. The infiltration also involved the pelvic retroperitoneal space. After contrast artery and measured 44 x 31 mm in axial view. Based on these clinical and radiological findings, the diagnosis of infected aneurysm of the right iliac artery was rendered. The patient was surgically treated 3 days after admission. She is alive and doing well 2 years after the operation. injection (Fig. 2), CT demonstrated a large aneurysm that was located in the proximal part of the right iliac JBR-BTR, 2012, 95: 350-354.

“…correction of mycotic aneurysm, organized thrombi surrounding disrupted aneurysm segments was supposed to block the communication between the disrupted aneurysm and pericardial space. CT scan is currently considered the modality of choice for diagnosis (8,9). In addition to demonstrating the size and extent of aneurysm, CT scan also demonstrates leak and perianeurysmal hemorrhage in a noninvasive manner.…”

We report a case of ruptured mycotic aneurysm involving innominate artery requiring an urgent surgical treatment. A 62-yr-old woman presented with fever and dyspnea. Previously, she was diagnosed with colon cancer and received right hemicolectomy and one cycle of adjuvant chemotherapy. On echocardiogram, pericardial effusion was noted and emergency pericardiocentesis was performed. CT scan revealed aortic aneurysm involving ascending aorta and innominate artery, and thrombi surrounding those structures. Patch repair of the defect in the ascending aorta and ringed Goretex graft to bypass the innominate and ascending aorta were performed. We believe that this is the first case of ruptured mycotic aneurysm involving innominate artery.
