摘　　要：目的　评价孤立肺结节 (SPN)的CT征象及其在鉴别诊断中的价值。方法　对 71例SPN(周围型肺癌 40例 ,结核瘤 2 1例 ,炎性假瘤 10例 )的CT征象进行回顾性分析。列举 18个征象进行统计。常规CT检查 71例 ,高分辩CT(HRCT)检查 44例。结果　 18个CT征象中有鉴别意义的主要征象有深分叶征、空泡征、空气支气管征、毛刺、棘状突起、血管支气管集束征、钙化、卫星灶和周围支扩征。HRCT显示这些征象较清楚。结论　不同性质的SPNCT征象有所不同 ,注意识别和分析这些征象有助于提高诊断的准确性。Objective To evaluate the CT findings of solitary pulmonary nodule (SPN) and the copability of CT in differential diagnosis. Methods The CT findings of 71 cases with SPN (40 patients with peripheral lung cancer, 21 patients with tuberculoma and 10 patients with inflammatory pseudotumor) were analyzed. 18 main signs were recorded. Standard CT were performed in all patients and high resolution computed tomography (HRCT) were performed in 44 patients. Results The main signs in differential diagnosis of SPN included: deep lolulation, vacuol sign, air bronchogam, spiculation, spiculate protubeance, bronchovascular convergence, calcificataon, satellites and peripheral bronchiectasis. These signs were demorstrated more clearly in HRCT than in standard. Conclusions SPN of various nature are of the specific signs. therefor, careful recogniztion and analyse of the signs would help to increase the diagnostic level.
