Methods The CT and X-ray film of 25 cases diagnosed clinically as spherical pneumonia were analysed retrospectively.Results CT features of 25 patients were summarized as follow : ⑴Lesions were usually located in the posterior lung fields.(2)The central part of the lesions showed high density, while periphery part of lesion were low in density and blurred. (3)The bilateral margin of lesions were straight, and the lesions appeared square or triangular in shape. ⑷Margins of the lesions may be irregular and blurred. ⑸There were marked pleural reaction around the lesions and some times pleura diffusely thickening occurred. ⑹Vascular marking around the lesions were exaggerated increase and thickened, nevertheless they were not stiff. Conclusion CT is valuable in diagnosing and differential diagnosing spherical pneumonia.
