Diagnosis: Mycoplasma pneumoniae pneumonia
Radiologic Findings: Chest radiograph shows diffuse bilateral ground-glass opacity especially in periphery with increased interstitial markings in both lungs. HRCT scans show multifocal patchy areas of consolidation and ground-glass attenuation with interlobular septal thickening in both lungs.
Brief Review: The most common finding on radiography was the presence of air-space opacification (n = 24, total 28), which was patchy and segmental (n = 9) or nonsegmental (n = 15) in distribution. On high-resolution CT, areas of ground-glass attenuation were seen in 24 patients (86%) and air-space consolidation in 22 (79%). In 13 patients (59%), the areas of consolidation had a lobular distribution evident on CT. Nodules were seen more commonly on high-resolution CT (25 of 28 patients, 89%) than on radiography (14 patients, 50%). In 24 (86%) of the 28 patients, the nodules had a predominantly centrilobular distribution on CT. Thickening of the bronchovascular bundles was identified more commonly on CT (23 of 28 patients, 82%) than on radiography (five patients, 18%).
