MSCT在结节或肿块型肺结核中的诊断价值

The diagnostic value of MSCT of nodules or masses type pulmonary tuberculosis

目的通过对比结节或肿块型不典型肺结核与周围型肺癌的MSCT表现,旨在提高结节或肿块型不典型肺结核诊断及鉴别诊断能力。方法收集我院2015年1月~2018年12月不典型肺结核103例,同期周围型肺癌患者96例,对比分析两组MSCT平扫及强化结果。结果深分叶征、短毛刺征、胸膜凹陷征、血管集束征、空洞内壁不光整、轻-中度或明显强化在周围型肺癌中出现率高,差异有统计学意义(P<0.05)。浅分叶征、长毛刺征、卫星灶、钙化、轻度及环形强化在结节或肿块型肺结核中出现率高,差异有统计学意义(P<0.05)。结论浅分叶征、长毛刺征、卫星灶、钙化、轻度及环形强化是结节或肿块型肺结核较特征性MSCT表现,征象出现越多,越提示结节或肿块型肺结核。

Objective To improve the diagnostic and differential diagnostic ability of nodular or mass atypical tuberculosis by comparing CT findings of nodular or mass atypical tuberculosis with peripheral lung cancer.Methods We retrospectiely reviwed 103 patients with atypical tuberculosis and 96 patients with peripheral lung cancer who underwent CT.Results Deep lobulation sign,short spicule sign,pleural indentation sign,blood vessel cluster sign,hollow inner wall irregularity,mild to moderate or obvious enhancement had a high incidence in peripheral lung cancer(P<0.05).The incidence of superficial lobulation sign,long burr sign,satellite focus,calcification,mild enhancement and mild enhancement in tuberculosis of nodular or mass type was higher(P<0.05).Conclusion Superficial lobulation sign,long spicule sign,satellite focus,calcification and mild enhancement in CT can represent nodule or mass tuberculosis to some extent.The sign appears more,the more hints nodular or bump tuberculosis.
