Ultrasound-guided fine-needle aspiration biopsy (US-guided FNAB) was performed in 40 patients with solitary pulmonary nodules (SPNs) for evaluation of diagnostic results and complication rates. The final diagnoses of the 40 patients included 30 malignancies and 10 benign lesions. Using US-guided FNAB, the diagnostic yields were 97% (29/30) in malignancies and 60% (6/10) in benign lesions. Of the 29 patients with cytologically proven malignancies, 12 underwent surgical resection. The correlation between cytological results and histologic diagnoses in these 12 was excellent (100%). The size of the nodule did not affect the diagnostic rate or complication rate. Only two patients (5%) developed minimal pneumothorax after US-guided FNAB. We conclude that US-guided FNAB is a useful, safe, and convenient diagnostic tool for SPN, and that malignant pulmonary nodules are more easily diagnosed than benign nodules.
对40例孤立性肺结节（SPN）患者进行了超声引导下细针穿刺活检（US引导下FNAB），以评估诊断结果和并发症发生率。40例患者的最终诊断包括30例恶性肿瘤和10例良性病变。使用US引导下FNAB，恶性肿瘤的诊断率为97%（29/30），良性病变的诊断率为60%（6/10）。在29例经细胞学证实为恶性肿瘤的患者中，12例接受了手术切除。这12例患者的细胞学结果与组织学诊断之间的相关性极佳（100%）。结节大小不影响诊断率或并发症发生率。仅2例患者（5%）在US引导下FNAB后出现轻微气胸。我们得出结论，US引导下FNAB是一种用于SPN的有用、安全且便捷的诊断工具，并且恶性肺结节比良性结节更容易诊断。
