Multifocal Brain Abscesses Due to Streptococcus intermedius

Brain abscess is a life-threatening illness that occurs when an intracerebral infection leads to cerebritis and subsequent pus formation within a well-vascularized capsule. While streptococci (aerobic, anaerobic, and microaerophilic) are the most common bacteria isolated, its presentation as multifocal brain abscesses is rarely described. In this report, we describe a 43-year-old male patient who presented to the emergency department due to progressive lethargy and low-grade fever of seven days worsening. Upon further evaluation, the patient was found to have multiple brain abscesses secondary to Streptococcus intermedius, confirmed by the culture of stereotactic aspiration of brain collection. This case underlines the importance of considering Streptococcus intermedius as a cause of multifocal brain abscesses.
