Group B streptococcal (GBS) bacteremia with mycotic thoracic aortic aneurysm and suppurative pericardial effusion.

Mycotic aortic aneurysm associated with suppurative pericardial effusion is a rare and serious clinical phenomenon that is linked with significant morbidity and mortality. We report a case of a 78-year-old man who presented with purulent pericardial effusion with tamponade physiology in association with a progressively enlarging, transverse aortic arch, mycotic aneurysm due to group B streptococci. To our knowledge, this is only the second reported case of this nature. Despite advances in the current era of antibiotics and surgical techniques, early diagnosis and aggressive treatment remain sentinel to successful management of the cardiovascular complications of group B streptococcus bacteremia.
