ABSTRACT
Infective endocarditis (IE) is a widespread condition marked by the infection of native or prosthetic heart valves, the endocardial surface, or an indwelling cardiac device. While native-valve IE is uncommon, patients with IE represent a diverse spectrum. Some respond well to treatment with few complications, while others face severe complications and an increased risk of mortality. Various factors contribute to this outcome, including delayed diagnosis, underlying health conditions like immunocompromised status or chronic diseases, and intravenous drug use. The most prevalent causes of IE are typically streptococci and staphylococci. IE attributed to Corynebacterium species is an exceptionally rare phenomenon, especially in individuals lacking conventional risk factors. This report presents a distinctive case involving Corynebacterium endocarditis in a 63-year-old female with a medical history encompassing intracranial aneurysm, hypothyroidism, and alcoholic cirrhosis. The patient's initial symptoms included shortness of breath, neck pain, and generalized weakness. Despite an initial focus on mild flu-like symptoms and a suspected urinary tract infection, subsequent evaluation unveiled pancytopenia and positive blood cultures for Corynebacterium striatum, culminating in the diagnosis of mitral valve endocarditis. This intricate clinical scenario, replete with numerous complications, underscores the significance of considering unusual pathogens in atypical presentations of IE. It prompts further exploration into the underlying mechanisms contributing to such infrequent occurrences.
