摘　　要：目的分析肺小结节的影像学和临床特征。方法对７６例肺内孤立小结节病例进行回顾性分析，总结其特征。结果恶性肿瘤４４例，良性病变３２例。良、恶性组小结节边缘不清者分别占１２％和３８％；有毛刺者分别占１８％和４５％；有钙化者分别占２５％和３％。恶性病变以肺泡细胞癌多见，占４５％；良性病变以结核较多见，占４４％。４５岁以下、４６～５９岁及６０岁以上组恶性肿瘤分别占２０％、６３％和７８％。结论小结节边缘不清、有毛刺和钙化是确定小结节良恶性的主要依据。４５岁以上的小结节以恶性病变多见。Purpose To study the imaging and clinical feature of solitary pulmonary small nodule (SPSN).Methods Seventy six cases of SPSN were retrospectively analysed.The diameter of SPSN≤20mm.Results There were 32 benign and 44 malignant lesions in our group.An unclear edge、thorn and calfication of SPSN are 12%,18%,25% in benign group and 38%,45,3% in malignant group respecttively.Pulmonary alveolus cell carcinoma is the most common type in the malignant group (45%) and tuberculosis is the most common type in the benign group (44%).The proportion of malignant disease is 20%、63% and 78% respectively.Conclusion Anunclear edge and thorn are the major evidences of malignant lesion;Calfication indicates a benign disease.The proportion of malignant is increased with age.
