摘　　要：目的　分析限局性机化性肺炎的CT ,特别是高分辨率CT(HRCT)的表现特点。方法回顾性对照分析 9例经组织学证实的限局性机化性肺炎 ,9例均行常规CT扫描 ,病灶部位行HRCT扫描 ,2例行增强扫描。结果　 9例病灶最大直径 2～ 4cm (平均 2 .5cm)。除 1例位于肺野内距胸膜3cm处外 ,余 8例均邻近胸膜面。病灶呈圆形或类圆形结节状 4例 ,不规则多边结节形 5例 ,6例边缘呈弓形凹陷 ,与病灶中心层面相邻的上下层面多呈不规则形。于肺窗上 4例可见病灶邻近肺野内有不同程度的渗出性病变。结论　限局性机化性肺炎的CT ,特别是HRCT表现有一定特征 。Objective To analyze the CT, especially HRCT appearance of localized organizing pneumonia. Methods The CT scans of nine patients with histologically proved localized organizing pneumonia were studied retrospectively. Results The size of the lesions in nine cases varied from 2 to 4 cm( average 2.5 cm). Eight lesions were located in the peripheral lung parenchyma near the pleural surface. The lesions were detected as round in four, anomaly in five. The margin of six lesions had inward bow indentation. Infiltrating lesions in surrounding structures were found in four cases. Conclusion The CT, especially HRCT appearance of localized organizing pneumonia shows some features that can make most of them to be differentiated from other lesions.
