尘肺病并发肺结核的CT表现特征分析

Analysis of CT features of pneumoconiosis complicated with pulmonary tuberculosis

目的 探讨尘肺病并发肺结核的CT表现特征,以期提高其诊断水平。方法 回顾性收集广州市胸科医院2022年1—12月诊治的尘肺病患者92例,其中并发肺结核患者46例为研究组,未并发肺结核患者46例为对照组。通过对两组患者的CT征象对比研究,分析尘肺病并发肺结核的CT表现特征。结果 研究组空洞、实变、树芽征、蜂窝状影、斑片影及胸膜增厚、积液的检出率分别是36例(78.26%)、18例(39.13%)、29例(63.04%)、7例(15.22%)、18例(39.13%)、17例(36.96%),高于对照组[分别是4例(8.70%)、2例(4.35%)、6例(13.04%)、0例(0.00%)、4例(8.70%)、6例(13.04%)],差异均有统计学意义(P均<0.05)。结论 相比单纯尘肺病,尘肺病并发肺结核CT上更易检出空洞、实变、树芽征、蜂窝状影、斑片影及胸膜增厚、积液。

Objective Exploring the CT features of pneumoconiosis complicated with pulmonary tuberculosis in order to improve its diagnostic level.Methods Retrospective collection of 92 patients with pneumoconiosis treated at Guangzhou Chest Hospital from January to December 2022,including 46 patients with concurrent pulmonary tuberculosis as the study group and 46 patients without concurrent pulmonary tuberculosis as the control group.By comparing the CT signs of two groups of patients,analyze the CT features of pneumoconiosis complicated with pulmonary tuberculosis.Results The detection rates of cavity,consolidation,tree bud sign,honeycomb shadow,patchy shadow,pleural thickening,and effusion in the study group were 36 cases(78.26%),18 cases(39.13%),29 cases(63.04%),7 cases(15.22%),18 cases(39.13%),and 17 cases(36.96%),respectively,higher than those in the control group(4 cases(8.70%),2 cases(4.35%),6 cases(13.04%),0 cases(0.00%),4 cases(8.70%),and 6 cases(13.04%),respectively),and the differences were statistically significant(P<0.05).Conclusion Compared to simple pneumoconiosis,pneumoconiosis complicated with pulmonary tuberculosis is more likely to detect cavities,consolidations,dendritic signs,honeycomb shadows,patchy shadows,pleural thickening,and effusion on CT.
