Viral pneumonia CT imaging manifestations are diverse and the lesions progress rapidly, with few large solid lesions, cavity formation and pleural effusion.
Viral pneumonia CT imaging performance is complex and varied, common manifestations of lobular distribution of ground glass shadow, small nodular foci, patchy solid shadow, can also be manifested as reticulated cord shadow, bronchial vascular bundles thickening, etc., there can be some interstitial changes. Typical characteristics of the early stage of the lesion, subpleural or bronchial, perivascular distribution of round-like ground glass shadow.
Viral pneumonia foci progress more rapidly, and severe patients often have multiple foci. In contrast, viral pneumonia is slow to absorb and has a longer duration of illness.
Viral pneumonia rarely has large solid shadows and pleural effusion, and seldom forms a cavity manifestation, which can be formed when combined with bacterial infection.
Different viruses cause pneumonia and different conditions of individuals will lead to differences in CT manifestations of the lungs, it is recommended to consult the doctor in time, combined with other relevant laboratory tests for comprehensive diagnosis.
