Left‐sided infective endocarditis presenting with pulmonary involvement and liver abscess: A case report

Key Clinical Message Infective endocarditis is an important differential diagnosis in patients with persistent fever and chills not responding to antibiotics and involvement of multiple organs. It can present without any specific signs such as valvular murmurs and no growth on blood cultures. Therefore, considering an echocardiography can be crucial and helpful in establishing the diagnosis. Infective endocarditis (IE), a rare disease with high mortality, arises from microbial infection affecting the heart valves and endocardium. It exhibits diverse symptoms and can involve various organs, including the brain, lungs, spleen, and liver. Diagnosis is often intricate due to its polymorphic nature, and negative blood cultures can add complexity to the diagnostic process. In this report, we present an unusual case of IE in a 53‐year‐old male farmer with multi‐organ involvement, including liver abscesses and pulmonary infiltration with cavities. Echocardiography showed a nodular mass attached to his bicuspid aortic valve, thus, playing a crucial role in confirming the diagnosis. This atypical manifestation highlights the necessity for increased clinical vigilance and further research to improve diagnostic approaches for uncommon IE cases.
