[Empyema of the gallbladder in an 8-year old boy].

A case of empyema of the gallbladder in a eight year old child is reported. The child presented simptoms relatively constant in the hydrops of the gallbladder, nomely abdominal pain usually confined to the right upper quadrant and or epigastrium, fever, nausea, vomit, dehidratation; a tender abdominal mass was palpable. As usually occurs in childhood, the acute distension of the gallbladder followed in this report, to preceding focus of infection (angina and cervical lymphadenopathy). Ultrasonography permitted to address the correct diagnosis. This was later confirmed at surgery and from histopathologic study.
