Pneumococcal native aortic valve endocarditis with mycotic abdominal aortic aneurysm, paraspinal and iliopsoas abscesses and pneumonia revealing a multiple myeloma.

ABSTRACT

We report a rare case of multiple myeloma presenting with native aortic valve endocarditis with secondary embolic mycotic abdominal aortic aneurysm, contiguous paraspinal and iliopsoas abscesses, and pneumonia due to Streptococcus pneumoniae in a Chinese man. He was treated with aortic valve replacement, endovascular stenting of aneurysm, image-guided drainage of abscesses, and a 6-week course of endocarditic antibiotic therapy followed by chronic suppressive antibiotic therapy. Cases of multiple myeloma presenting with invasive pneumococcal infection were reviewed.
