球形肺炎的CT诊断(20例分析)

The CT Diagnosis of Globular Pneumonia and the Analysis to 20 Cases

目的：通过分析球形肺炎的ＣＴ特征，进一步提高对它的认识，以便与其它脑内球形病变区别。材料和方法：收集２０例经临床抗炎治疗后完全吸收而证实的球形肺炎，进行回顾性分析。结果：球形肺炎的ＣＴ特征为１）病灶与胸膜交界处见“方形征”１２例：２）病灶中心较边缘高者１０例：３）病灶内可见支气管气相者６例：４）病灶远肺门侧胸膜增厚者１４例：５）病灶近肺门侧肺纹理粗１２例：６）抗炎治疗后复查２－３周内完全吸收１６例。结论：球形肺炎的ＣＴ表现具有一定特征性，诊断性治疗对鉴别诊断极为重要。

objective: By analysis the CT characteristics of globular pneumonia, we can know it well and distinguish it from other globular. lesion in the lung. Materials and methods Collect 20 cases of globular preumonia which are confirmed to be the disease after the treatment of antibiotics and made the retrospective analysis. Results, The CT characteristics of globular pneumonia are (1) there are 'square signs' between the lesion and pleura in 12 cases. (2)The density in the lesion center is higher than the edges in 10 cases.(3)There are bronchus gas image in the lesions in 6 cases (4)There is pleural thickening far from the hilus of lung to the lesion in 14 cases (5)There are increased brochovascular shadows near the hilus of lung to the lesion in 12 cases. (6)The lesions are completety absorbed in 2-3 weeks after the treatment of antibiotics in 16 cases Conclusion: The CT signs of globular pneumonia are characteristic. The diagnostic treatment is very important to the differential diagnoses.
