To explore the clinical value of CT-guided percutaneous needle biopsy (PCNB) for diagnosis of atypical pulmonary tuberculosis.
The data from 15 patients undergoing diagnostic PCNB for pulmonary tuberculosis were retrospectively analyzed. Prior to PCNB, definitive diagnosis failed to be obtained from other examinations including sputum smear in 10 cases, fiberoptic bronchoscopy in 12, chest X-ray in 13, CT scan in 15, and position emission tomography (PET) with CT examination in 1 case.
Sputum smears and fiberoptic bronchoscopy both failed to produce positive results and pulmonary and/or mediastinal lesions were shown by chest X-ray, CT, and PET-CT. Pulmonary tuberculosis were diagnosed in the 15 cases by histopathological examination following PCNB, and pneumothorax in relation to PCNB occurred in 3 cases and hemoptysis in 1 case.
PCNB provides a safe and accurate means for diagnosis of pulmonary tuberculosis when imaging and other diagnostic modalities fail to result.
探讨CT引导下经皮肺穿刺活检（PCNB）对非典型肺结核诊断的临床价值。
回顾性分析15例因肺结核接受诊断性PCNB患者的数据。在PCNB前，10例患者经痰涂片、12例经纤维支气管镜检查、13例经胸部X线、15例经CT扫描以及1例经正电子发射断层显像（PET）联合CT检查均未能明确诊断。
痰涂片和纤维支气管镜检查均未得到阳性结果，胸部X线、CT及PET-CT显示肺部和/或纵隔病变。PCNB术后经组织病理学检查确诊15例为肺结核，PCNB相关气胸3例，咯血1例。
当影像学检查和其他诊断方法无法确诊时，PCNB为肺结核的诊断提供了一种安全、准确的方法。
