目的:总结球形肺炎的CT特征,提高CT诊断水平。方法:收集经临床及病理证实的23例球形肺炎的CT资料,对其进行分析研究。结果:主要CT表现为:(1)病灶多位于肺下叶背侧近胸膜处;(2)病灶孤立呈圆形,楔形及方形,大小3～11cm;(3)边缘模糊,不规则;(4)病灶与胸膜接触面广;(5)增强扫描病灶不均匀强化,内见清晰的略低密度灶。结论:CT薄层扫描减少组织间的重叠,有利于发现有诊断价值的征象,结合临床症状为球形肺炎的诊断提供帮助。
Objective: To summarize the CT features of spherical pneumonia and improve the diagnostic value of CT. Methods: CT data of 23 cases of spherical pneumonia confirmed by clinical and pathology were collected and analyzed. Results: The main CT manifestations were as follows: (1) the lesions were mostly located in the dorsal lower lobe of the lung near the pleura; (2) the lesions were isolated in the shape of circle, wedge and square with the size of 3 ~ 11cm; (3) 4) extensive contact area between the lesion and the pleura; (5) enhanced scan lesion heterogeneous enhancement, see within the clear slightly lower density lesions. Conclusion: CT thin-layer scanning can reduce the overlap between the tissues, which is helpful to find the diagnostic value of the signs, combined with clinical symptoms of spherical pneumonia diagnosis help.
