Case 1. (a) CT scan chest coronal view demonstrating subpleural reticulation within the periphery of the lung as well as thin-walled cysts of various sizes (arrows). (b) CT chest using maximum intensity projection protocol demonstrating areas with the most disease activity and least vasculature (circle).

Three targets were premarked in the left lower lobe (LLL) for case 1 (Figure 2) and four targets in case 2 (two in the right upper lobe and two in right middle lobe) (Figure 3); all of them were at one cm from the pleura.
Preprocedure mapping for case 2 using the Medtronic superDimension Navigation System, version 7, Minneapolis, USA. Two targets were premarked in RML and two in the right upper lobe (RUL).
