      Abstract

      We retrospectively assessed the computed tomography (CT) features of 31 intrapulmonary lymph nodes (IPLNs) with histopathologic correlations. CT scans revealed that the IPLNs are located in the subpleural region, frequently below the level of the carina, and angular in shape. Most of the IPLNs are solid in texture but occasionally present with a ground-glass appearance. For pleura-attached and pleura-separated IPLNs, one or more and 3 or more linear opacities extending from the nodules can be identified, respectively. Histologically, the IPLNs are located either at the junction of the pleura and lung lobules or at the junction of adjacent lung lobules.
