title: [Diagnosis of mycoplasma pneumonia in children: which is the role of thoracic radiography?].
abstract: Despite its frequency, pneumonia is often surprisingly difficult to diagnose in children and young adults. In particular, the etiologic agent of pneumonia is difficult to recognize in an early stage, which obviously implies an empirical or delayed treatment. Chest radiography is one of the most common procedures required when pneumonia is suspected. This retrospective study was carried out to investigate the capabilities of chest radiography to identify the specific patterns of mycoplasma pneumonia in children. The chest radiographs of 76 children and adolescents (aged 4.2 to 16.4 years) with a radiographic diagnosis of pneumonia were reviewed. All patients were tested twice for serum antimycoplasma antibodies. Thirty-eight subjects (50%) with markedly increased antimycoplasma antibody levels were diagnosed as having mycoplasma infection. In the remaining 38 patients, viral (22 patients, 29%), bacterial (13 patients, 17%) and mixed (3 patients, 4%) infections were diagnosed on the grounds of clinical and laboratory data. Parahilar peribronchial infiltrates were found to be associated with both viral and mycoplasma infections, whereas segmental or lobar consolidation was associated with bacterial, viral and mycoplasma infections. Reticulonodular infiltrates were a specific pattern of mycoplasma pneumonia. The authors conclude that, in the presence of a reticulonodular infiltrate in a lobe, mycoplasma pneumonia can be confidently diagnosed.
