The author examined computed tomographic (CT) scans of the chest from 40 patients with cultures positive for atypical mycobacteria. Common manifestations included bronchiectasis, air-space disease, nodules, and scarring and/or volume loss. Less commonly observed signs were cavities, lymphadenopathy, and pleural disease. Serial scans were obtained in 10 patients and showed new areas of bronchiectasis and progression of existing bronchiectasis, suggesting that the bronchiectasis was not a preexisting condition but resulted from infection. The anatomic distribution of the above findings was diffuse, not strongly favoring any lung zone. The identification of multifocal coexistent bronchiectasis, air-space disease, and nodules at CT should raise the possibility of atypical mycobacterial lung disease, even in an otherwise healthy patient.
作者检查了40例非典型分枝杆菌培养阳性患者的胸部计算机断层扫描（CT）。常见表现包括支气管扩张、气腔病变、结节以及瘢痕形成和/或肺容积缩小。较少见的表现有空洞、淋巴结病和胸膜疾病。对10例患者进行了系列扫描，结果显示出现了新的支气管扩张区域以及现有支气管扩张的进展，提示支气管扩张并非既往就有的情况，而是由感染所致。上述表现的解剖分布是弥漫性的，对任何肺叶均无明显偏好。即使在其他方面健康的患者中，CT上发现多灶性并存的支气管扩张、气腔病变和结节，也应提高非典型分枝杆菌肺病的可能性。
