Mycotic aneurysm rupture of the descending aorta

Abstract

A 69-year-old diabetic male with salmonella bacteremia developed hypovolemic shock and swelling of the neck. A CT examination revealed massive mediastinal hemorrhage extending into the neck soft tissues caused by false aneurysm rupture of the descending thoracic aorta. Aortography showed continuous extravasation from a large leak at the medial side of the descending thoracic aorta. Although surgical intervention was immediately performed, the patient died 3 weeks later from multiple-organ failure. In this report, CT and angiographic findings of mycotic aneurysm rupture are presented and a review is given.

Spontaneous retropharyngeal hematoma: An unusual presentation of thoracic aortic dissection

“…The fourth case, a diabetic man, was admitted with salmonella septicemia and 2 days post-admission developed a large neck swelling and severe hypovolaemic shock (16). CT revealed a large hemorrhage in the mediastinum extending to the cervical soft tissues and a leakage from the descending aorta.…”

Infected aortic aneurysm and inflammatory aortic aneurysm—In search of an optimal differential diagnosis

“…Infected aortic aneurysm may show rapid growth in size, accompanied by a pseudoaneurysm or a perforated or penetrated aneurysm [5], therefore, diagnostic imaging may have to be repeated if the clinical suspicion persists [23]. Non-or delayed treatment of infected aneurysm often leads to a fatal outcome due to fulminant sepsis, aorto-enteric fistula formation, and rupture [14,24].…”

Salmonella-related mycotic pseudoaneurysm

“…8,9 Computed tomography is the most useful imaging modality. 10,11 Surgical interventions, in addition to parenteral antibiotic therapy for at least 6 weeks, 11,12 are required to:…”
