Categorization of the radiographic findings of M. pneumoniae pneumonia.
(a) Lobar or segmental consolidation. Posteroanterior chest radiograph shows a homogenous dense opacity in the right upper lobe. An air-bronchogram was also noted in the consolidative lesion in the right upper lobe. (b) Patchy infiltration. Posteroanterior chest radiograph demonstrates localized ill-defined increased lung opacity in the base of the right lower lobe. (c) Localized reticulonodular infiltration. The chest radiograph shows localized reticulonodular lesions in the base of the right lower lobe. (d) Parahilar peribronchial infiltration. The chest radiograph demonstrates extensive parahilar reticulonodular lesions in the left upper and lower lung fields.

Determination of the dominant radiographic finding.
(a) A 15-year-old boy with Mycoplasma pneumoniae pneumonia. Chest radiograph shows lobar consolidation in the left lower lobe and parahilar peribronchial infiltration in the left lung. In this case, lobar consolidation was regarded as the dominant finding, and categorized as lobar or segmental consolidation. (b) Chest radiograph of a 9-year-old girl with Mycoplasma pneumoniae pneumonia shows both a localized reticulonodular opacity and a patchy opacity in the right upper lung. In this case, the focal reticulonodular opacity was regarded as the dominant finding, and categorized as localized reticulonodular infiltration.
