WebMorphology included density, size (the maximum diameter), shape (round, oval, or irregular), margin (smooth, lobular, spiculated, or lobular and spiculated), pleural tag, vascular cluster, bubble lucency, and air bronchogram.

WebTumors with ALK rearrangement were more likely to have well defined border and bubble lucency. Wang et al. demonstrated five CT characteristics had significant difference between ALK rearrangement and EGFR mutation, including tumor size, ground-glass opacity (GGO), bubble-like lucency, lymphadenopathy, and tumor shadow …
WebLocation. Most expansile, lucent lesions are located in the medullary space of the bone. However, we can further define the location of the lesion by noting its relationship to the physis. Many lesions tend to occur in a “favorite” part of the bone. The favored locations are listed in the figure below. Webwith internal bubble lucency on high-resolution CT (HRCT), is an early finding of BAC(12). The result of 2-[fluorine-181-fluoro-2-deoxy-D-glucose (FDG) positron emission tomography(PET), however, may be nega tive(12 - 14). In addition, presumably because of spar se cellularity, we have experienced false negative
