Childhood pneumonia due to brucellosis: A case report

Abstract

Rationale: Childhood brucellosis is a significant community health problem. It may imitate other conditions and may be misdiagnosed. Pulmonary involvement is a rare complication of childhood brucellosis.

Patient concerns: A 23-month-old child was referred to our hospital with a 3-week history of fevers and cough. He was initially diagnosed with pneumonia.

Diagnoses and interventions: Conventional antibiotic treatment was ineffectual. Total leukocyte count was 10,300/mm, hemoglobin was 8.5 g/dL, and platelet count was 250,000/mm. The erythrocyte sedimentation rate and procaicltonin were 25 mm/h and 0.12 ng/mL, respectively. Chest radiography showed pneumonic infiltrate in both lungs.The initial bacteriologic test results were negative. Ten days after admission, Brucella melitensis were isolated from the second blood culture. This child was cured with the 2-drug regimen (rifampin+trimethopicin-sulfamethoxazole) for 6 weeks.

Outcomes: The child recovered well with no occurrence of complications. The child remained asmptomatic without any signs or symptoms at a follow-up of 1 year.

Lessons: Non-specific findings of pulmonary brucellosis in children often make diagnosis difficult. The second blood culture is essential. In endemic areas, children with fevers and cough should be included in the diagnosis in cases of pulmonary brucellosis.
