The selection of equipment largely depends on the availability of technology, expertise, and the characteristics of the nodule and patient. Radial EBUS (r-EBUS) is often combined with these techniques for real-time confirmation of the nodule location. A bronchus sign is considered to have a higher diagnostic yield when biopsy tools can directly reach the nodule. We describe a case series of creating a false airway into the nodule when an eccentric r-EBUS signal is seen to subsequently obtain a concentric signal.Keywords: peripheral pulmonary nodule, radial EBUS, diagnosis
