Streptococcus milleri liver abscess presenting as fulminant pneumonia.

A case of a young man who developed a Streptococcus milleri liver abscess secondary to an occult colonic foreign body, which presented as fulminant community acquired pneumonia, is reported. The isolation of Streptococcus milleri, a normal member of the gastrointestinal flora, from an abscess, blood or sputum should prompt a search for pathology, foreign bodies or silent perforation in the gastrointestinal tract.
