CT features of adult mycoplasma pneumoniae pneumonia

Objective: To observe the CT features of mycoplasma pneumoniae pneumonia. Methods: CT features of 40 adult patients with serologically proven mycoplasma pneumoniae pneumonia were retrospectively reviewed. Results: The most common CT findings of mycoplasma pneumoniae pneumonia were ground-glass opacity (34/40, 85.00%) and consolidation (28/40, 70.00%). The other findings included nodules (18/40, 45.00%), thickening of the bronchovascular bundles (6/40, 15.00%), interlobular septal thickening (6/40, 15.00%), mediastinal lymphadenopathy (6/40, 15.00%) and pleural effusion (4/40, 10.00%). Most of the ground-glass opacity and consolidation showed tendency of lobular distribution and involving the lower lobes. In some patients, the absorption of the lesions was slower than the relief of symptoms. Conclusion: CT findings of mycoplasma pneumoniae pneumonia have some features, and can provide help for the diagnosis of mycoplasma pneumoniae pneumonia.
