EBUS-TBNA sampling techniques vary greatly among interventional pulmonologists. One of those variations is the fanning technique, which consists of sampling multiple areas within a lymph node in each pass by using the “up–down” lever of the EBUS scope. Fanning technique is especially used in endoscopic ultrasound-fine needle aspiration for pancreatic lesions1. It could be argued that one of the drawbacks of performing an EBUS-guided mediastinal cryobiopsy (Cryo-EBUS) is that it is limited to taking a sample from a single area of the lesion since the 1.1mm cryo-probe (Erbecryo 20402-401, Tubingen, Germany) is inserted through a single pathway created by the FNA puncture. We show the case of a 52-year-old man with an enlarged subcarinal lymph node (station 7) localized by EBUS and a fine needle aspiration (FNA) was performed using a 22-G needle (SonoTip TopGain; Medi-Globe, Rohrdorf, Germany). After the FNA was performed, the 1.1mm cryoprobe was introduced gently under ultrasound guidance through the single pathway created by the FNA puncture; once inside the lymph node we performed the fanning technique, positioning the cryo-probe in the desired area by moving the lever of the EBUS scope up or down (Fig. 1). Three cryobiopsies were taken in three different areas of the lymph node by freezing for 5s with no complications. The diagnosis was compatible with small cell lung carcinoma.
