Objective :To assess the overall value of lobulation sign and deep lobulation sign in the differential diagnosis of peripheral lung cancer and pulmonary tuberculoma in CT images.Methods : Firstly , articles about CT differential diagnosis between pulmonary tuberculoma and peripheral lung cancer were selected ,which were published in the period(from January 1990 to December 2008),and useful data were extracted.Then Meta-analysis was done using Meta-disc software,and SDOR value calculated.

方法搜集1990年1月至2008年12月国内外公然发表的关于四周型肺癌与肺结核球CT鉴别诊断的文献，对文献进行筛选，应用Meta-disc软件对符合条件的原始研究进行质量评估、异质性检验，计算阳性似然比、阴性似然比和诊断比值比，最后汇总敏感性和特异性，绘制SROC曲线并计算曲线下面积来综合评价分叶征及深分叶征在CT检查中对于四周型肺癌与结核球鉴别诊断的价值，进行敏感性和特异性分析。

Abstract］ objective to study the knowledge of the imaging manifestation of x-ray and ct in peripheral small lung cancer.methods to collect twenty cases with no symptom in early time diagnosed by clinic and to retrospectively analyze their imaging features.results x-ray appeared patch,small node.ct appeared patch,small node,light lobulation,peripheral vessel convergence,pleural indentation sign.most of the diameter was 1.5 to 2 cm,with no mediastinum and pulmonary hilar lymph nodes diversion.furthermore the clinical symptom was not obviously.conclusion to be familiar and handling the sign mentioned above is the key to boost the diagnosis of small peripheral lung cancer.

目的 探讨周围型小肺癌的x线、ct影像学表现。方法收集临床和病理证实的早期无症状肺癌20例，对其影像学进行回顾分析。结果本组早期肺癌x线为斑片状、小结节状。ct表现为斑片状、小结节状、轻度分叶状肿块，小毛刺、血管集束征、胸膜凹陷征，大多直径在1.5～2 cm。无纵隔淋巴及肺门转移，且临床症状不明显。结论熟悉并掌握上述征象是提高小肺癌早期诊断率的关键。
