Right lobar pneumonia complicated by sub-phrenic abscess in a child.

ABSTRACT

A 14-year old boy presented with chest and abdominal pain and fever for one week. He had been treated with several antibiotics at home and in a peripheral hospital for respiratory infection. Physical examination showed features of right lobar pneumonia and peritonitis. Chest radiograph showed consolidation in the right lower lung field and abdominal ultrasonography showed a subphrenic collection. At exploratory laparotomy, a right subphrenic abscess and general peritonitis without an intra-abdominal focus were found. The abscess was drained and broad-spectrum antibiotics given. Death, however, occurred from overwhelming infection. Subphrenic abscess complicating pneumonia is unusual but can be the cause of poor response to treatment. The diagnosis should be excluded in a child with pneumonia and persisting abdominal symptoms. Prompt treatment is necessary to avoid morbidity and mortality.
