Objective: To analyze the imaging features of mycoplasma pneumonia in order to improve the early diagnosis and treatment of mycoplasma pneumonia as well as reduce misdiagnosis. Methods:Multislice CT data of 31 mycoplasma pneumonia patients during 2012.4 to 2014.4 in our hospital were retrospectively analyzed. Results:Multislice CT results showed that 22 cases(70.97%) occurred in one side of lung, in which 12 cases (38.71%) located in the left lung(two cases located in the lobi superior(6.45%)and 10 cases located in the lobi inferior(32.26%));10 cases (32.26%) located in the right lung , in which 4 cases located on the lobi superior (12.90%), four cases at the lobi inferior(12.90%), two cases involved both lobi medius pulmonis and lobi inferior(6.45%). 9 cases (29.03%) were double lung involvement. The changes of CT are diverse which included glass-like images, consolidation, air bronchogram, bronchial vascular bundle thickening, pleural effusion and mediastinal lymph nodes enlargement. Conclusion:Patients with mycoplasma pneumonia always have varied radiographic changes and chest multislice CT has a certain sense of early diagnosis.
