28例早期周围型小肺癌的X线、CT影像学表现

目的：探讨周围型小肺癌的X线、CT影像学表现。方法：收集临床和病理检查已证实的早期无症状周围型小肺癌28例，对其影像学进行回顾分析。结果：本组早期肺癌X线片表现为斑片状、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—3cm。无纵隔及肺门淋巴结转移，临床症状不明显。结论：熟练掌握上述征象是提高周围型小肺癌早期诊断率的关键。

X-ray and CT manifestation to display early small peripheral lung cancer

Objective：To study the knowledge of the imaging manifestation of X-ray and CT in peripheral small lung cancer. Methods：To collect 28 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 convergenee,pleural indentation sign. Most of the diameter was 1 to 3 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.
