Salmonella typhimurium infection of thoracic aorta aneurysm in immunocompetent subject. Case report and literature review.

The authors describe a Salmonella typhimurium infection of thoracic aorta aneurysm in an immunocompetent subject. The patient, a 62-year-old male, was found to have recurrent S. typhimurium bacteremia despite multiple antibiotic treatments. A roentgenogram of the chest, which was normal on admission, revealed the presence of a first arch enlargement of the heart shadow. A computed tomography confirmed the diagnosis. Surgical resection of the aneurysm was carried out with in situ prosthetic graft interposition. The surgical specimen culture yielded S. typhimurium. The postoperative course was uneventful. Twenty-four months after discharge the patient remained well. A review of English language literature is presented.
