RT Journal Article SR Electronic T1 Image of the month: Mycotic aortic arch pseudoaneurysm due to Salmonella enterica JF Clinical Medicine JO Clin Med FD Royal College of Physicians SP 580 OP 581 DO 10.7861/clinmed.2022-0404 VO 22 IS 6 A1 Chunyan Jiang A1 Hongwei Li YR 2022 UL http://www.rcpjournals.org/content/22/6/580.abstract AB A 61-year-old man with hypertension and psoriasis, which was treated with adalimumab, was admitted after a 1-month history of fever following a dental implantation. Computed tomography of the chest revealed a pseudoaneurysm in the aortic arch, and blood culture grew Salmonella enterica. A diagnosis of mycotic pseudoaneurysm of the aortic arch due to Salmonella was made, and he was treated with cefoperazone–sulbactam. During his hospital stay, he developed hoarseness followed by haemoptysis, and underwent thoracic endovascular aortic repair followed by emergency open surgical repair. However, he died 5 weeks after the surgery due to acute upper gastrointestinal bleeding, which was confirmed as an aortoesophageal fistula by oesophagogastroscopy.
