Computed tomographically guided injection of cyanoacrylate in association with preoperative radioguided occult lesion localization of ground-glass opacities.

Intraoperative localization of a ground-glass opacity (GGO) is difficult because it is not easy to palpate and may be invisible at radioscopy. Therefore various techniques have been developed to improve intraoperative localization of these lesions, allowing adequate surgical resection. We report 2 cases of preoperative localization of GGOs through computed tomographically guided injection of cyanoacrylate in association with radioguided occult lesion localization (ROLL).
