摘　　要：目的：分析32例肺内结核性肉芽肿CT征象，以提高对该病的诊断水平。方法回顾性分析32例肺内结核性肉芽肿的临床资料、CT表现，所有病例均经穿刺活检或支气管镜检查后病理证实。全部患者均行螺旋 CT 扫描，其中5例行 CT 增强扫描。结果51例肺内结核性肉芽肿中32例出现了“支气管树爬行征”，即病灶有沿支气管血管束由外周斜向肺门生长的趋势，外侧部分较内侧大。结论“支气管树爬行征”是肺内结核性肉芽肿的特征性CT征象，可以帮助与肺癌等其他肺疾病鉴别。Objective To study a characteristic CT sign of pulmonary tuberculosis granuloma and improve the diagnostic accuracy of the disease.Methods The clinical data and CT findings of 32 cases with pulmonary tuberculosis granuloma were retrospectively analyzed.All cases were pathologic confimed by bronchoscopy or biopsy.All the patients had spiral CT scan,of which five had CT enhancement.Results In 51 cases of pulmonary tuberculosis granuloma 32 had＆quot;Crawling Sign＆quot;,which showed the trend that le-sions from the peripheral spread to the hilum of lung along the bronchovascular bundle with the outer part larger than the inside,like a lesion crawled along the bronchial tree.Conclusion The＂Crawling Sign＂is a quite characteristic CT sign of the tuberculous granu-loma which can help to differentiate tuberculous granuloma from lung cancer and other lung diseases.
