Isolation of Eikenella corrodens from polymicrobial hepatic abscess: report of one case.
Eikenella corrodens is a rare cause of hepatic abscess. We report a case of a hepatic abscess caused by (1) Bacteroides fragilis, (2) Streptococcus constellatus and (3) E. corrodens, which illustrates potential problems of antibiotic coverage due to the presence of Eikenella species. The infection followed an episode of acute gastroenteritis and the clinical course appeared indolent evolving over one week. Besides empirical antibiotics, initial percutaneous aspiration was performed and yielded pus which grew E. corrodens concomitantly with Streptococcus species. E. corrodens was sensitive to penicillin but resistant to clindamycin and metronidazole. But B. fragilis was resistant to penicillin. So the antibiotics were switched to amoxicillin/clavulanate. Unfortunately fever persisted and the abscess increased in size. Therefore echo-guided percutaneous drainage with pigtail catheter was installed. Fever subsided 5 days later. After 21 days treatment of antibiotics, the patient was discharged in good condition despite having some sterile fluid in the residual abscess cavity. Two months after discharge the follow-up echogram confirmed complete resolution of the residual abscess. This patient shows us the existence of E. corrodens in pediatric patients, especially when the hepatic abscess is very likely from the spread of an oral or abdominal infection.
