Ultrasonographic characteristics of lymph nodes as predictors of malignancy during endobronchial ultrasound (EBUS): A systematic review.

•Ultrasonographic features of mediastinal lymph nodes can predict malignancy.•Central hilar structure and heterogeneous echogenicity are the strongest predictors.•Ultrasonographic features may reduce unnecessary repeat endobronchial ultrasounds.•Inconsistency in reported predictive ability suggests more research is needed.•Predictive tools can be developed based on these ultrasonographic features.
