Epidemic adenoviral lower respiratory tract infection in pediatric patients: Radiographic and clinical characteristics

OBJECTIVE. This retrospective study was undertaken to evaluate the radiographic and clinical findings of adenoviral lower respiratory infection during an epidemic period. CONCLUSION. Epidemic adenoviral pneumonia may mimic bacterial pneumonia on radiographs. Findings that include bilateral and multifocal involvement on chest radiographs, normal or decreased WBC associated with lymphocytosis, and progression of illness despite extensive antibiotic therapy, help to differentiate epidemic adenoviral from bacterial pneumonia.
