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. 第十七頁(yè)，共三十頁(yè)。Solid and Groundglass ponents實(shí)性與磨玻璃實(shí)性與磨玻璃 (bō l237。)樣樣n Another result from screening studies is that nodules containing a groundglass ponent are more likely to be malignant (5).n 另一項(xiàng)研究表明，含有磨玻璃另一項(xiàng)研究表明，含有磨玻璃 (bō l237。)樣密度的結(jié)節(jié)很可能是惡性樣密度的結(jié)節(jié)很可能是惡性結(jié)節(jié)。結(jié)節(jié)。n Partly solid lesions with groundglass ponents had a malignancy rate of 63%. 部分實(shí)性和磨玻璃樣密度是惡性結(jié)節(jié)的可能性事部分實(shí)性和磨玻璃樣密度是惡性結(jié)節(jié)的可能性事 63%n Nonsolid only groundglass lesions had a malignancy rate of 18%. 完全完全磨玻璃樣密度結(jié)節(jié)磨玻璃樣密度結(jié)節(jié) 16%是惡性結(jié)節(jié)是惡性結(jié)節(jié)
