Abstract: Anginosus group streptococci (previously known as Streptococcus
milleri group) comprise three subspecies known to cause endogenous pyogenic
infections. The majority of cases reported are in adults. We report a liver
abscess occurring in a 3-year-old child without known preceding factors. He
presented with clinical signs and X-ray findings compatible with a lower
respiratory tract infection and was treated with oral amoxicillin. A blood
culture grew Streptococcus constellatus and an abdominal ultra sound scan
revealed a liver abscess confirmed by computerized tomography scan.
Conservative management with a prolonged course of antibiotics led to complete
resolution. Anginosus group streptococci can cause liver abscesses in healthy
children and the presence of bacteremia due to this group of organisms should
prompt investigation for occult abscesses.
