title: Streptococcus pneumoniae, an emerging pathogen in mycotic aneurysms?
abstract: Two patients are described with a mycotic aneurysm caused by streptococcus pneumoniae infection. The patients presented with back pain and fever, and had an antecedent history of lower respiratory tract infection; neither of them were suffering from endocarditis. Mycotic aneurysms are a rare disorder with, over the years, a changing spectrum of presentation, localisation and bacterial aetiology. S. pneumoniae infection has only very rarely been reported as a cause of mycotic aneurysms. Since 1986, 14 patients with a mycotic aneurysm were treated at the Leiden University Hospital. Of these patients, 5 had mycotic aneurysms caused by S. pneumoniae infection. The mortality in these patients was high. In this communication, we would like to draw attention to S. pneumoniae infections as an emerging cause of mycotic aneurysms.
