Abstract

|
|
|
Infectious arteritis is a rare complication of liver abscess, and infectious arteritis involving multiple arterial sites with pseudoaneurysm formation has not been described previously. A 74-year-old man treated for liver abscess complained of abdominal and neck pain. Abdominal computed tomographic angiography (CTA) revealed a decrease in the size of the liver abscess, but also disclosed a pseudoaneurysm in the distal descending thoracic aorta was newly noted. Neck CTA revealed arteritis with abscess formation in the left internal carotid artery (ICA). Follow-up CTA after antibiotic therapy showed a decrease in the size of the left ICA abscess and a significant increase in the size of the aortic pseudoaneurysm. To prevent the rupture of the pseudoaneurysm, an endovascular stent graft was used. The final CTA revealed the disappearance of the aortic pseudoaneurysm with good apposition of the grafted stent. The patient has been monitored for 3 years with no new clinical events.
