Insights
Round pneumonia, a lower respiratory infection with round opacity on chest X-ray, is typically seen in young children. This case highlights a rare presentation in a 10-year-old girl successfully treated with antibiotics.
Area of Science:
- Pediatrics
- Radiology
- Infectious Diseases
Background:
- Round pneumonia commonly affects children under 8 years old, characterized by lower respiratory tract infection and radiographic round opacities.
- It is infrequently diagnosed in older children due to more developed collateral airways.
Observation:
- A 10-year-old girl presented with symptoms of fever and cough.
- Chest X-ray revealed rounded densities, indicative of pneumonia.
- A rapid urinary antigen test for Streptococcus pneumoniae was positive.
Findings:
- The patient was diagnosed with round pneumonia, a condition typically seen in younger children.
- Treatment with penicillin and gentamicin led to complete clinical and radiographic recovery.
- Mycoplasma pneumoniae infection was ruled out by negative antibody tests.
Implications:
- This case expands the known age range for round pneumonia presentation.
- It underscores the importance of considering bacterial pneumonia in older children with atypical radiographic findings.
- Prompt diagnosis and appropriate antibiotic therapy are crucial for favorable outcomes in round pneumonia.
Abstract:
Round pneumonia is a disease that occurs mainly in young children who have a clinical presentation of lower respiratory tract infection together with a chest radiograph showing round opacity. The mean age of patients with round pneumonia is five 5 years; it is uncommonly seen after the age of 8, as the collateral airways tend to be well developed by this age. In our case, we evaluated a 10-year-old girl who presented with fever, cough, and rounded densities on her chest x-ray. The rapid urinary antigen test for Streptococcus pneumoniae was positive, and serum anti-Mycoplasma pneumoniae antibodies were non-reactive. The diagnosis of round pneumonia was confirmed when the patient showed a complete recovery both clinically and radiographically after a course of penicillin and gentamicin.
