Evaluation of ground-glass opacity cases diagnosed by bronchoscopy

Conclusions: GGO cases can be possibly diagnosed by EBUS-GS depending on the findings of blizzard sign. In addition, adenocarcinoma in-situ or minimally invasive carcinoma that presents as GGO on CT scan often exhibits weak cellular atypia, which can be interpreted as class 3 on cytology. In such cases, evaluation of EGFR mutation might contribute the diagnosis.
