Transesophageal bronchoscopic ultrasound‐guided fine‐needle aspiration (EUS‐B‐FNA)—Pushing the boundaries in the diagnosis

Isolated mediastinal adenopathy is a diagnostic challenge in the paediatric population, often requiring invasive surgical procedures for diagnosis. We describe a novel minimally invasive modality in a 20 month toddler—transesophageal bronchoscopic ultrasound‐guided fine‐needle aspiration (EUS‐B‐FNA). This is the youngest reported use of this modality, highlighting feasibility, technical issues, safety, and rapid diagnosis leading to expedited treatment.
