Chest radiographs of patients with suspected bronchogenic carcinoma occasionally show two adjacent opacities in the same lobe, one located centrally, the other more peripherally. Case histories and chest radiographs of five patients with these findings are presented. In each case, the centrally located mass was shown to be a bronchogenic carcinoma, while the more peripherally located density proved to be a pulmonary infarct. It is thus important to perform a biopsy of the proximal lesion rather than the peripheral one. The location and size of the infarct with respect to the bronchogenic carcinoma, as well as the possible cause of the infarct, are reviewed.
疑似支气管源性癌患者的胸部X光片偶尔会显示同一肺叶内两个相邻的不透明区，一个位于中央，另一个更靠近周边。本文介绍了五例有这些表现的患者的病史和胸部X光片。在每例病例中，位于中央的肿块被证实为支气管源性癌，而更靠近周边的致密影则为肺梗死。因此，对近端病变而非周边病变进行活检很重要。本文还回顾了肺梗死相对于支气管源性癌的位置和大小，以及梗死的可能原因。
