Streptococcal Mycotic Abdominal Aortic Aneurysm Rupture in an Asplenic Patient

This study concerns a 69-year-old asplenic man who presented with abdominal pain and was found to have a contained rupture of a true infrarenal abdominal aortic aneurysm (AAA). Isolates of debrided aortic wall and swab cultures identified β-haemolytic Streptococci group A, a bacterium which typically causes pharyngeal and skin infections and may also initiate invasive infection associated with multi-organ failure. Following prompt surgical and antibiotic treatment, our patient was alive and well 6 weeks following surgery.
