Streptococcus intermedius Bacteremia and Pyogenic Liver Abscess in a Patient With No Risk Factors

Abstract

This case report depicts a 39-year-old male with no significant past medical history who was admitted for fever of unknown origin and sepsis. He was then found to have Streptococcus intermedius bacteremia and pyogenic liver abscess. The treatment course was complicated by pleural empyema leading to readmission. The case presented here adds to the medical literature, where a clear underrepresentation has been noted, and outlines a unique case of S. intermedius liver abscess complicated by pleural empyema in a patient without significant medical history, risk factors, or typical physical exam findings.

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

“…We reviewed the available medical literature by PubMed with the keywords “ Streptococcus intermedius ” AND “lung abscess”, “pleural effusion” and “pleural empyema” from 1993 to 2023, published in English. We found 34 articles meeting the inclusion criteria ( Table 2 ), of which 4 described concomitant brain and lung abscesses, but none reported the presence of lung and brain abscesses due to S. intermedius associated with left sided endocarditis [ 1 , 2 , 8 , 9 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 ]. Only one paper [ 8 ] described the case of a lung and brain abscess associated with Chiari network endocarditis in the right heart.…”
