CT引导下经皮肺穿刺活检诊断老年患者肺炎性假瘤的价值

目的探讨CT引导下经皮肺穿刺活检诊断老年患者肺炎性假瘤的价值。方法选择2010年2月～2012年12月本院怀疑为肺周围肿瘤并行CT引导下经皮肺穿刺活检诊断的老年患者32例，全部患者经术后病理确诊，分析经皮肺穿刺活检资料，评价其诊断率。结果本组患者术前CT引导下经皮肺穿刺活检诊断为炎性假瘤．术后病理检查确诊为炎性假瘤30例，腺癌1例，结核1例；CT引导下经皮肺穿刺活检诊断与病理诊断的符合率为93．8％（30／32）；肺活检后并发少量气胸2例，经卧床休息及吸氧后自行吸收；咯血1例，经对症治疗后出血停止。结论CT引导下经皮肺穿刺活检诊断老年患者肺炎性假瘤的准确率较高，并发症轻微，安全性较好．值得临床应用。

The value of CT-guided percutaneous needle biopsy diagnosis of pul- monary inflammatory pseudotumor in elderly patients

Objective To investigate the value of CT-guided percutaneous needle biopsy diagnosis of pulmonary in- flammatory pseudotumor in elderly patients. Methods 32 cases of elderly patients suspected with lung cancer in our hospital from February 2010 to December 2012 were given CT-guided percutaneous needle biopsy diagnosis,all the patients were confirmed by pathologically,percutaneous lung biopsy data was analyzed to evaluate diagnostic rate. Re- suits All the patients were diagnosed with inflammatory pseudotumor by preoperative CT-guided pereutaneous needle biopsy,postoperative pathologic diagnosis showed 30 cases of inflammatory pseudotumor,one case of tuberculosis,and one cases of adenocareinoma,the compliance rate of CT-guided percutaneous lung biopsy and pathological diagnosis of was 93.8%（30/32）;After lung biopsy,two cases of small pneumothorax and one case of emptysis were found,and they all recovered after symptomatic treatment. Conclusion The accuracy rate of CT-guided pereutaneous needle biopsy diag- nosis of pneumonia in elderly patients with pseudotumor is highly,with slight complication,good security,and it is wor- thy of application.
