Understanding of Community-acquired Pneumonia
on the basis of chest computed tomography imaging

Computed tomographic (CT) scans are now working in many general hospitals in Japan. Most of the
Japanese clinicians can use CT scans as one of the useful tool of the examination of community-acquired
pneumonia. Chest CT imaging plays an important role in the accurate interpretation of pulmonary
anatomy and pathology. Mycoplasma pneumoniae pneumonia and Chlamydophila pneumoniae pneumonia
demonstrate centrilobular or acinar shadows, and thickening of bronchivascular bundles on CT imaging.
Characteristic findings of Legionella pneumophila pneumonia on CT are sharply demarcated peribronchovascular foci of consolidation intermingled with ground glass opacity. It is possible to estimate the
pathogenic bacteria, if there are characteristic features on CT imaging on the basis of clinical information.
