Although diffuse, these nodules may show a predominance in the lung bases due to the higher perfusion there (2). Prevascular nodes lie anterior to the great vessels ( Figs. The location and number of lymph nodes involved is an important aspect of cancer staging. On the other hand, the larger a node is, the more likely it is to represent a significant abnormality.
