Lung abscess is a very rare infectious condition in children and is most commonly encountered as a complication of bacterial pneumonia. The majority of patients with lung abscess show an excellent response to antibiotic therapy and only in a minor group of cases, simple drainage or other surgical interventions are required. Empiric parenteral antibiotic therapy is the gold standard in treatment of lung abscess in children. Here we present a 2.5 year-old girl who developed lung abscess during the course of a lobar pneumonia and required percutaneous drainage due to failure of resolution with conventional antibiotic therapy.
