A 55-year-old man was diagnosed with infective endocarditis( IE) of the mitral valve caused by Streptococcus sanguinis. His IE was controlled immediately after the initiation of intravenous antibiotic therapy lasting for 4 weeks. A few days before surgery, he complained of abdominal discomfort and computed tomography (CT) scan revealed rupture of the mycotic iliocolic artery aneurysm. ⋯ After additional 4 weeks' intravenous antibiotic therapy, the mitral valve was replaced. Mycotic visceral artery aneurysms are rare in IE. Early diagnostic approaches and interventions such as TAE are crucial.
