Streptococcus intermedius Brain Abscess with Lung Abscess and Aortic Valve Endocarditis: A Case Report and Literature Review

Abstract

Streptococcus intermedius is frequently associated with brain and liver abscesses, while pleuropulmonary infections are considered rarer. Even less frequent is the association of lung and brain abscesses due to this agent with infective endocarditis. We describe the case of a 40-year-old man complaining of cough, fever, and headache who was diagnosed with a brain abscess due to S. intermedius, a concomitant lung abscess, and aortic native valve endocarditis. He was treated with surgical drainage of the brain abscess and a 4-week course of intravenous ceftriaxone, followed by oral amoxicillin/clavulanate, obtaining healing of the lesions without relapse of the infection.

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

“…reported a patient with aortic valve endocarditis and severe aortic regurgitation that presented with unilateral pulmonary edema. In another article, Francesca Gavvaruzi et al 13 . reported a patient with aortic valve endocarditis and lung abscess.…”

“…In a case report, Rana Al-Zakhari et al 12 reported a patient with aortic valve endocarditis and severe aortic regurgitation that presented with unilateral pulmonary edema. In another article, Francesca Gavvaruzi et al 13 reported a patient with aortic valve endocarditis and lung abscess. In our case, the patient had multiple lung lesions while having aortic valve endocarditis.…”

Lung abscess: an update on the current knowledge and call for future investigations

“…or mycobacteria [1]. Isolation of unusual pathogens, even in immunocompetent individuals, should carefully be considered as a cause of disease [20–22]. Hemoptysis may occur in LA, and may in rare cases be due to complicating pulmonary artery aneurysms [22].…”
