Chest radiographic (mainly CT), and pathological findings in pulmonary infarction associated with lung cancer were studied to obtain information useful for the interpretation of CT findings, and to help determine the cause of infarction. Sixteen cases of lung infarction were chosen from among 518 cases of lung cancer. All patients were operated on between January 1980 and December 1990. Sixteen surgical cases and one autopsy case all with evidence of lung cancer and infarction were chosen. There were 13 men and 4 women with a mean age of 56 years. Adenocarcinoma was found in 8 cases, squamous cell carcinoma in 6, adenosquamous carcinoma in 2, and small cell carcinoma in 1. Chest radiographs and CT revealed infarction shadows in 8 of the 16 cases. Typical CT findings for pulmonary infarction were: shadows located in the same lobe and periphery as the cancer; ill-defined, 10-25 mm nodular shadows; and lesions located both in the subpleural zone and apart from the pleura. Lesion counts in each area were about the same. Observation of one patient for 2 months revealed a decrease in the size of the nodular shadows and clarification of their margins. In most cases, centrally extended cancer resulted in vascular stenosis and infarction.
对与肺癌相关的肺梗死的胸部影像学检查（主要是CT）及病理结果进行了研究，以获取有助于解读CT结果及辅助确定梗死原因的信息。从518例肺癌病例中选取了16例肺梗死病例。所有患者均在1980年1月至1990年12月期间接受了手术。选取了16例手术病例和1例尸检病例，均有肺癌及梗死证据。其中男性13例，女性4例，平均年龄56岁。腺癌8例，鳞癌6例，腺鳞癌2例，小细胞癌1例。胸部X线片和CT显示16例中有8例存在梗死阴影。肺梗死典型的CT表现为：阴影位于与癌症相同的肺叶及周边；边界不清的10 - 25毫米结节状阴影；病变位于胸膜下区域及远离胸膜处。各区域的病变数量大致相同。对1例患者观察2个月发现结节状阴影大小减小且边界变清晰。在大多数情况下，中央型扩展的癌症导致血管狭窄和梗死。
