Description
Summary:ABSTRACT Streptococcus constellatus, a member of the Streptococcus anginosus group, is a commensal bacterium that causes pyogenic infections, particularly abscesses. This report describes the case of a 28-year-old immunocompetent man who developed a brain abscess and epidural empyema after pneumonia. MRI suggested an abscess, which was confirmed by culture, revealing S. constellatus. Treatment included abscess drainage and ceftriaxone administration, which led to a full recovery. Diagnosis is challenging because of overlapping features with other bacteria. Imaging and culturing are crucial for identification. This case highlights the importance of considering S. constellatus in central nervous system infections, even in immunocompetent individuals.
