In April 1998, a 60-year-old man was admitted to the
hospital with productive cough and right upper quadrant abdominal
discomfort. About 2 years ago, he presented with persisted diarrhea and
abdominal pain. An infrarenal abdominal aortic aneurysm was evidenced
by the CT scan. He underwent a surgical resection of the aneurysm.
Bacterial cultures from the excised aorta grew Salmonella
enteritidis group O. A diagnosis of mycotic aneurysm was
established, and he was treated with IV ampicillin for 6 weeks.
