球形肺炎的影像诊断

Imaging diagnosis of spherical pneumonia.

目的探讨球形肺炎的影像学特点,以提高其诊断及鉴别诊断。方法回顾性分析26例球形肺炎的临床、X线及CT资料。结果球形肺炎发病大多数位于肺的背部,靠近或紧贴胸膜,可单发或多发,呈圆形、类圆形、方形、楔形,可见支气管气像、空泡征,病灶周围血管纹理增多、增粗,但不强直。结论影像学检查结合临床表现及实验室检查可明显提高球形肺炎的准确诊断及鉴别诊断能力。

Objective To study the imaging features of spherical pneumonia and to evaluate its diagnosis and differentiation.Methods The CT and X-ray film of 26 cases with spherical pneumonia clinically proved were analysed retrospectively.Results The site of spherical pneumonia most located in the back of the lung and near the pleura,single or multiple in number.CT appearance presented as spherial or square and triangular in shape with ＂air bronchogram＂and＂vacuole sign＂.Vascular marking around the lesions were exaggerated increase and thickened,nevertheless they were not stiff.Conclusion CT is valuable in diagnosis and differentiation of spherical pneumonia.
