Abstract
Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is becoming more common for diagnosing intrathoracic lymphadenopathy, including tuberculous lymphadenopathy. We herein report two cases of complications possibly related to EBUS-TBNA for tuberculous lymphadenopathy. The first patient was a 26-year-old woman who developed intrabronchial polypoid granulomas exclusively at puncture sites two months after undergoing EBUS-TBNA. Although endobronchial extension may occur, the risk of aggravation caused by puncture should be considered. The second patient was a 39-year-old woman with transient smear-positive bloody sputum that developed immediately after EBUS-TBNA and persisted for three days. Temporary isolation following EBUS-TBNA should be considered for possible tuberculous lymphadenopathy.
