Unusual diagnoses made by convex-probe endobronchial ultrasound-guided transbronchial needle aspiration

Abstract

Endobronchial ultrasound-guided transbronchial needle biopsy (EBUS-TBNA) has proven to be an effective and minimally invasive tool to diagnose and stage lung cancer. However, its use for the diagnosis of rare mediastinal and lung pathologies has been rarely described. Hereby we describe a retrospective chart review of our EBUS-TBNA database for unusual diagnosis made between July 2012 and October 2016. Those conditions considered unusual for EBUS-TBNA diagnosis were identified and their medical records reviewed.
