A GGN without a solid part. Preoperative CT shows a GGO lesion, 10 mm in diameter, without a solid part (a). The O-arm could not show the lesion. However, the location of the tumor could be inferred by comparing the positions of the peripheral pulmonary vessels (white arrowhead) or the bronchus near the tumor on the preoperative and intraoperative CT images (b). A PDS needle is placed as a marker (black arrowhead).
