We conducted a retrospective analysis of the epidemiological, etiological, clinical and radiological characteristics, and mainly of those related to the diagnosis and treatment, of all the patients with radiological criteria of solitary pulmonary nodule (SPN) studied in our environment during a period of six years (1984-1989). The incidence of SPN was 3.1% (123/3953). Among the 117 cases of filiated etiology, 83 (71%) were malignant and 34 (29%), benign thoracotomy was used as diagnostic method in 11 (32%) benign cases and in 8 (9.6%) malignant cases. Due to several causes, only 31 out of the 75 (41.3%) malignant nodules diagnosed prior to the thoracotomy underwent resection surgery. According to the selection criteria applied in our medium, a high number of the SPN were malignant; in most of these cases, the diagnosis was established without the need of thoracotomy and in less that half of them, curative surgery was attempted.
我们对在六年期间（1984 - 1989年）在我们的研究环境中根据影像学标准诊断为孤立性肺结节（SPN）的所有患者的流行病学、病因学、临床和放射学特征，主要是与诊断和治疗相关的特征进行了回顾性分析。SPN的发病率为3.1%（123/3953）。在117例有明确病因的病例中，83例（71%）为恶性，34例（29%）为良性。在11例（32%）良性病例和8例（9.6%）恶性病例中，开胸手术被用作诊断方法。由于多种原因，在开胸手术前诊断的75例恶性结节中，只有31例（41.3%）接受了切除手术。根据我们研究环境中应用的选择标准，大量的SPN是恶性的；在大多数这些病例中，无需开胸手术即可确诊，并且其中不到一半的病例尝试了根治性手术。
