Atypical Mycotic Aortic Aneurysms.

Mycotic aortic aneurysms are rare occurrences and such aneurysms associated with Streptococcus pneumoniae are seldom seen in the current antibiotic era. We present the unusual case of a 68-year-old healthy female with a Streptococcal mycotic abdominal aortic aneurysm of unknown etiology treated with antibiotics and open surgical intervention. Postoperative imaging revealed multiple new thoracic mycotic aortic aneurysms for which she was treated with thoracic endovascular aortic repair. Sequential abdominal and thoracic Streptococcal mycotic aortic aneurysms treated with a combination of open and endovascular surgery demonstrate a unique and rare case.
