Figure 2 Growth patterns of 15 ground-glass nodules (GGNs). The last larger symbols represent GGNs that were surgically resected. Of 15 GGNs with growth, seven were surgically resected. Two pure GGNs represented by a filled rectangle and a filled circle became part-solid GGNs at the last follow-up CT scans and were confirmed as invasive adenocarcinoma. One part-solid GGN represented by an inverted triangle showed increases in both the solid component and the whole size of the GGN.
