【文章內(nèi)容簡(jiǎn)介】 邊緣光滑見于良性結(jié)節(jié)，除外轉(zhuǎn)移瘤 第十四頁，共三十一頁。 Air Bronchogram sign 空氣支氣管征 ? Recent studies have showed that an air bronchogram is more monly seen in malignant pulmonary nodules. It is most monly seen in BAC (bronchoalveolar cell carcinoma) and adenocarcinoma. ? 最近一項(xiàng)研究說明，在惡性結(jié)節(jié)中經(jīng)?？匆娍諝庵夤苷?，主要見于支氣管肺泡癌或腺癌 第十五頁，共三十一頁。 ? The case on the left shows an airbronchogram seen as a linear lucency (broad arrow) and as a more cystic lucency (small arrow) due to the fact that the bronchus is seen en face. 第十六頁，共三十一頁。 ? On the left two solitary pulmonary nodules. Based upon the morphology, which lesion has the most malignant features? ? 以下兩個(gè)結(jié)節(jié)有哪些惡性特征呢 第十七頁，共三十一頁。 ? The lesion on the far left has a spicuated margin and has lucencies within it. The lesion next to it is lobulated in contour and has some spicules radiating to the pleura. It is however homogeneous in attenuation. Based on these findings we should be most concerned that the lesion on the far left is malignant. It proved to be an adenocarninoma, while the other one was a fungal infection. The lucencies and frank air bronchograms should not mislead you in thinking that it probably is infection. 第十八頁，共三十一頁。 Solid and Groundglass ponents 實(shí)性與磨玻璃樣 ? Another result from screening studies is that nodules containing a groundglass ponent are more likely to be malignant (5). ? 另一項(xiàng)研究說明，含有磨玻璃樣密度的結(jié)節(jié)很可能是惡性結(jié)節(jié)。 ? Partly solid lesions with groundglass ponents had a malignancy rate of 63%. 局部實(shí)性和磨玻璃樣密度是惡性結(jié)節(jié)的可能性事63% ? Nonsolid only groundglass lesions had a malignancy rate of 18%. 完全磨玻璃樣密度結(jié)節(jié) 16%是惡性結(jié)節(jié) ? Only solid lesions had a malignan
