Application of ultrasound-guided core biopsy to minimize the non-diagnostic results and the requirement of diagnostic surgery in extrapulmonary tuberculosis of the head and neck

摘要

Head and neck extrapulmonary tuberculosis (ETB) presenting as lymphadenopathy poses a great threat by potentially increasing the deterioration of clinical outcomes. Tissue sampling for diagnostic confirmation of ETB is the only invasive procedure during the entire clinical course. It is, therefore, necessary to establish ETB sampling methods with accuracy and minimal invasiveness.
