目的研究球形肺炎的CT征象特点,以便与其他球形病灶,特别是肺癌做出正确的鉴别诊断。方法搜集30例经临床证实的球形肺炎病人的CT与X线检查资料,并进行回顾性分析。结果30例球形肺炎的主要CT表现是,(1)病变两侧缘垂直于胸膜呈刀切样平直边缘,病变呈方形;(2)病变中央密度高,边缘密度低,显示晕圈状改变;(3)病变边缘可不规则,有锯齿状改变但较模糊;(4)周围胸膜反应显著,有较广泛增厚;(5)病变周围血管纹理增多、增粗、扭曲,但无僵直和受牵拉表现;(6)抗炎治疗后病变明显吸收缩小。结论CT检查对于球形肺炎的正确诊断与鉴别诊断是很有帮助的。
Objective To study the CT features of spherical pneumonia in order to make the correct differential diagnosis with other spherical lesions, especially lung cancer. Methods The CT and X-ray examination data of 30 clinically confirmed patients with spherical pneumonia were collected and retrospectively analyzed. Results The main CT manifestations of 30 cases of spherical pneumonia were (1) the flanking edge of the lesion was perpendicular to the flat edge of the pleura and the lesion was square; (2) the center of the lesion was high and the edge density was low, showing a halo change ; (3) the edge of the lesion may be irregular, jagged change but more obscure; (4) the surrounding pleural reaction was significant, more extensive thickening; (5) lesions around vascular texture increased, thickening, distorting, Pull performance; (6) anti-inflammatory treatment significantly reduced after the lesion. Conclusion CT examination of spherical pneumonia for the correct diagnosis and differential diagnosis is very helpful.
