Liver abscess following blunt trauma: a case report and review of the literature.

We report a case of Haemophilus paraphrophilus causing primary liver abscesses after blunt nonpenetrating trauma. A 32-year-old previously healthy white man sustained a back injury 2 months prior to admission with fever, chills, and night sweats. A computed tomography (CT) scan-directed needle aspirate of several hypoechoic hepatic lesions grew H paraphrophilus. Recent blunt trauma to the lower back may have contributed to the localization of this infection to an area of contusion or hematoma within the liver, followed by an episode of bacteremia that seeded the injury.
