摘要
目的了解肺部孤立性结节的性质及影像学特点。方法分析242例肺部孤立性结节的性质、影像学特点及两者的关系。结果 242例肺部孤立性结节的疾病谱常见依次为肺癌、肺结核、炎性假瘤。当结节直径为<1 cm、1-3 cm、3-5 cm、5-7 cm、≥7 cm时其恶性比分别为9.1%、42.8%、76.9%、91.2%、95.9%。纯磨玻璃样结节、半实质样结节、纯实质样结节,恶性比分别为80.3%、75.4%、62.9%。分叶征、毛刺征、空泡征等多见于恶性病变。结论我科收治的肺部孤立性结节中肺癌最多见,其次为肺结核、炎性假瘤。当结节直径≥5 cm其恶性概率达92.3%,纯磨玻璃样和半实质样结节较纯实质样结节恶性概率高。分叶征、毛刺征、空泡征等多见于恶性病变。
Objective To analyze the imaging characters and properties of solitary pulmonary nodule. Methods The imaging characters and properties of 242 solitary pulmonary nodule and their relationships were ana- lyzed. Results The most common diseases were lung cancer, followed by tuberculosis and inflammatory pseudotu- mor. When nodule diameter was less than 1 cm, its malignant proportion was 9.1%. When the diameter was among 1-3 cm, the malignant proportion 42. 8%, 3-5 cm to 76. 9% , 5-7 cm to 91.2%. When the diameter was bigger than 7 cm, the malignant proportion was 95.9%. Pure glass sample and essence mixed sample ( also known as a real sam- pie) nodules had higher possibility of malignance than pure substance sample nodules did. Lobulation, apiculation, and vocule were commonly found in malignant lesions. Conclusion The malignancy of lung space-occupying lesions increases with the increase of nodal diameter. Pure glass sample and essence mixed sample nodules have higher possi- bility of malignance than pure substance sample nodules do. Calcification, pure substance sample and lobulation have significant effect on benign and malignance of lung lesions. Lobulation, apiculation and vocule sign are commonly found in malignant lesions.
