Brain abscess due to Streptococcus MG-intermedius (Streptococcus milleri)

Abstract

Three cases of brain abscesses due to Streptococcus MG-intermedius are reported, and the literature pertaining to this subject is reviewed. The importance of careful and complete identification of these etiological agents of infection is stressed. The clinical presentation, the origin of S. MG-intermedius producing brain abscess, and its relation to hepatic abscesses and endocarditis are discussed.

Bilateral Tubo‐Ovarian Abscesses Four Years AfterTotal Abdominal Hysterectomy

“…S. intermedius in particular is almost always isolated from pyogenic central nervous system or liver abscesses and is rarely, if ever, isolated from the genitourinary tract. 7,8 This case report demonstrates the need to consider TOA in the differential diagnosis of a patient with a pelvic mass and abdominal pain, regardless of a history of prior hysterectomy. It also suggests that the current theory on TOA formation may only be a partial explanation of the pathophysiology of this complicated and life-threatening gynecologic condition.…”

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

“…However, the association between S. intermedius endocarditis and brain abscess is rarely reported. In fact, using the keywords "Streptococcus intermedius" AND "endocarditis" AND "brain abscess", we found 12 works, of which just 4 actually described cases of S. intermedius endocarditis with brain abscess [3,4,6,8], and 1 reported a case of S. intermedius brain abscess related to a patent foramen ovale [5] (Table 1). Pleuropulmonary infections due to Streptococcus intermedius are also considered uncommon [12]; however, in recent years, their importance has been increasingly recognized.…”

Focal Neurological Symptoms at Initial Presentation Could Be a Potential Risk Factor for Poor Prognosis Among Patients With Multiple Brain Abscesses by Streptococcus anginosus Group: A Case Report With Literature Review

“…In this study, we reviewed the present case and previous literature regarding poor prognostic factors related to neurological sequelae among multiple brain abscesses caused by SAG using PubMed with the search term "multiple brain abscesses", "Streptococcus milleri", "Streptococcus intermedius" and "Streptococcus anginosus". We include all the cases with multiple brain abscesses caused by SAG from the search result [5,[10][11][12][13][14][15]. Cases with epidural, subdural abscesses, or unknown neurological sequelae were excluded from the review.…”
