ABSTRACT
A 58-year-old man was admitted for pneumonia after several business trips to Thailand, Vietnam, and Malaysia. Despite resolution of pneumonia on chest X-ray, high fever persisted. CT scan revealed a juxtarenal, atypical-shaped abdominal aortic aneurysm of 4.5cm in size, and this was thought to be the cause of persisting fever. After prolonged antibiotic treatment, surgical resection and prosthetic tube replacement of the aneurysm was performed. The aneurysm was a pseudoaneurysm, and histological examination showed chronic inflammation with no atherosclerotic change. It was thought to be of mycotic origin. On the 12th day after operation, he became febrile, and an arterial blood culture yielded <i>Burkholderia pseudomallei</i>. Antibiotics chosen according to sensitivity tests, were given. He was finally discharged with no exidence of persisting infection, on the 55th day after operation.
