| Abstract |
Campylobacter fetus is a Gram-negative spiral-shaped small bacillus, which causes bacteremia and mycotic aneurysm in pregnant women or immunocompromised hosts. However, the reports of C. fetus mycotic aneurysm in immunocompetent hosts are rare. The male patient in his 60s, who have no comorbidities other than treatment history of hepatitis C in his 20s, appeared with fever of 38°C and right abdominal pain. CT scan revealed the aneurysm of right internal iliac artery, thus he was referred to our hospital for surgery. The one set of blood culture obtained at the timing of admission turned positive with Gram-negative spiral-shaped bacilli after 5 days incubation. The same bacilli were detected from aneurysm sample obtained after surgical resection as well, which were identified as C. fetus according to the result of biochemical tests, mass-spectrometry, and 16S ribosomal RNA analysis. Most of the previous cases of C. fetus mycotic aneurysm were occurred in abdominal aorta according to our literature search. The cases in internal iliac artery and the cases in immunocompetent hosts were rare. In order to reveal clinical features of C. fetus intra-vascular infections more, the more case reports of C. fetus mycotic aneurysm occurred in arteries other than abdominal aorta or in immunocompromised hosts are demanded. |
