Infective endocarditis caused by Escherichia coli is rare but its incidence is increasing, with a high mortality compared to the HACEK group. While E. coli is common in bacteremia, it rarely causes endocarditis. Diagnosis is based on positive blood cultures and echocardiography showing vegetations. Pyomyositis, another bacterial infection predominantly affecting immunocompromised individuals, can be caused by E. coli. We describe the case of a woman with sepsis and the rare association of endocarditis and pyomyositis due to E. coli, resulting in a fatal outcome. Treatment includes third-generation antibiotics and intensive monitoring. Surgical intervention may be necessary in severe complications.
