Introduction: Bronchopneumonia is an inflammatory lung condition involving one or more lobes, characterized by patchy infiltrates commonly caused by Streptococcus pneumoniae (30–50% of cases), followed by Staphylococcus aureus and Klebsiella pneumoniae in more severe infections. Clinical manifestations include high fever, restlessness, dyspnea, rapid and shallow breathing accompanied by rales, vomiting, and either dry or productive cough. Respiratory infections may trigger inflammatory responses that increase excessive mucus production. Case Illustration: A 1-year-5-month-old girl weighing 7.9 kg presented to RSUD Ir. Soekarno Sukoharjo with shortness of breath and intermittent fever for six days, accompanied by vomiting, decreased appetite and fluid intake, cough, weakness, runny nose, and oral sores. Physical examination revealed a weak general condition, compos mentis consciousness, dyspnea, wheezing, and fine wet rales in both lung bases. Dysmorphic facial features consistent with Down syndrome were observed. Laboratory findings showed leukopenia, eosinopenia, and elevated RDW-CV, while chest radiography indicated bilateral bronchopneumonia. Management included intravenous fluids, antibiotics, antipyretics, antiemetics, and bronchodilators. The patient was diagnosed with sixth-day fever due to bronchopneumonia, mild-to-moderate dehydration, recurrent nausea and vomiting, atrial septal defect, and Down syndrome.
