An analysis was made of bullous emphysema detected by plain chest radiography and computed tomography (CT). Bullous lesions were detected in 43 of 214 patients who had thoracic CT as a further assessment of their pulmonary, pleural, and mediastinal abnormalities. Plain chest radiography failed to detect the bullous lesions in 17 (39.5%) out of the 43 patients. Bullous lesions unrecognizable on plain radiographs ranged from 1.0 to 2.0 cm in size, were few in number, and were situated on the mediastinal side of the lung in many patients. CT is a sensitive method for detecting bullous lesions. Therefore, we consider it necessary to perform CT when needle biopsy for a previously known pulmonary lesion is taken into account, because knowledge of coexisting bullous lesions may be useful in preventing the occurrence of severe pneumothorax as complication.
对通过胸部X线平片和计算机断层扫描（CT）检测出的大疱性肺气肿进行了分析。在214例因肺部、胸膜和纵隔异常而接受胸部CT进一步评估的患者中，有43例检测出大疱性病变。在这43例患者中，有17例（39.5%）的大疱性病变在胸部X线平片中未被检测到。在X线平片上无法识别的大疱性病变大小在1.0至2.0厘米之间，数量较少，且许多患者的病变位于肺的纵隔侧。CT是检测大疱性病变的敏感方法。因此，我们认为在考虑对先前已知的肺部病变进行针吸活检时，有必要进行CT检查，因为了解并存的大疱性病变可能有助于预防严重气胸作为并发症的发生。
