[Management of pediatric liver abscess]

Liver abscess in the pediatric population remains uncommon in developed countries, except in cases of septicemia or in children with major debilitating diseases, granulocyte dysfunction, or immunosuppression. Although much is known about the etiopathogenesis of liver abscess, the gold standard of investigations and treatment is still debatable in developing countries. We report the case of a 6-year-old child living in Reunion Island, with no medical history, presenting with right and pyretic abdominal pain in the right upper quadrant. Ultrasound and CT scan showed a large hypodense nonenhanced area in segment IV. Final diagnosis was, by exclusion, pyogenic liver abscess based on negative serology, recent liver lesion, and normal tumor test results, even if blood culture remained negative. No percutaneous puncture was done because of positive outcome after 4 days of antibiotics. Treatment consisted in three intravenous antibiotics (ceftriaxone, aminoxide, and metronidazole) until complete biological normalization. Ultrasound remained normal 3 months later. Even if liver abscess is uncommon in developing countries, the diagnosis must be raised in cases of isolated liver tumor with fever. Management in the nonimmunosuppressed child must be discussed associating parenteral antibiotic therapy, percutaneous drainage, or surgery in very uncommon cases, according to the liver location and first day's progression. Etiological investigation such as colonoscopy in adults must be adapted to pediatric data.
