摘　　要：目的:探讨局灶性磨玻璃征(Ground Glass Opacity GGO)对早期周围型肺癌的诊断价值。方法:搜集临床、CT资料完整,经手术病理证实的早期周围型肺癌27例(28个),对其CT表现,作一回顾性分析。结果:28个早期周围型肺癌直径均<2.0cm,呈园形或卵园形22个,其中纯GGO或部分GGO密度的有21个,并见有毛刺14个,血管集束征14个,胸膜凹陷13个,分叶征10个和小泡征8个。结论:局限性GGO为早期周围型肺癌重要CT征象之一,若同时具备下列4项中的一项或多项高度提示早期小肺癌:①结节呈圆或卵圆;②内部见实性结节(即部分GGO);③伴有分叶、毛刺、血管集束征、胸膜凹陷征等其它恶性征象;④短期复查未变化。Objective：To evaluate the value of focal area of ground glass opacity GGO in diagnesis of early peripheral lung ancer by MIX..Methods： Twenty-seven patients with 28 peripheral lung nodules were discovered by CT. And, all of those nodules were proved to be small lung cancer by surgery and histo-pathology. Thln-slice section CT was performed in every patient. Results： Among the 28 nodules, the maximal diameter of the nodules were less than 20mm n = 28, round or oval shape n = 22, focal areas of pure GGO opacity mixed with isolated dense consolidaton n = 21, vascular convergence sign n = 14, spur formation n = 14, lobulation n = 10, and vacuolar sign n = 8. Conclusion： An oval or round ground-glass opacity nodule of lung is one of the important signs of malignancy. Authors believed that when a GGO nodule combined with signs of round or oval shape, part solid, vascular convergence, spur formation, lobulation or pleural indentafionetc, an early lung carcinoma should be highly suspected.
