目的回顾性分析14例球形肺炎的HRCT(高分辨率CT)表现,以提高该病的诊断符合率。方法采用GEHispeed Nx/i双排螺旋CT机,层厚10mm,螺距1.5,对病变区加作2mm层厚,1~2mm间隔,骨重建的HRCT扫描。用肺窗、纵隔窗对病变进行观察摄影。结果病灶多位于肺野背侧,病灶为椭圆形或尖端指向肺门的楔形,“晕征”6例,“方形征”8例,肺门侧粗长毛刺6例,胸膜广泛增厚12例,所有病例随诊证实诊断。结论HRCT是鉴别球形肺炎和周围型肺癌及其它肺肿块的有效手段。
Objective To retrospectively analyze the HRCT (high resolution CT) manifestations of 14 cases of spherical pneumonia in order to improve the diagnostic coincidence rate of the disease. Methods The GEHispeed Nx / i double-row spiral CT was used. The slice thickness was 10mm and the pitch was 1.5. The lesion area was treated with 2mm slice thickness, 1 ~ 2mm interval and bone reconstruction HRCT scan. Lung window, mediastinum window to observe the lesion photography. Results Most of the lesions were located in the dorsal flank of the lung. The lesions were oval or pointed to the wedge of the hilar. There were 6 cases of “halo sign”, 8 cases of “square sign”, 6 cases of hilum burr on the hilar side and extensive pleura Thickened in 12 cases, all cases confirmed diagnosis. Conclusion HRCT is an effective method to identify spherical pneumonia and peripheral lung cancer and other lung masses.
