Abstract

Patients with suspected tuberculosis without pulmonary lesions and with intrathoracic lymphadenopathy often pose a diagnostic challenge. The aim of this study was to describe the diagnostic utility of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) in patients with isoleted intrathoracic lymphadenopathy due to tuberculosis (TB). Cases with tuberculous lymphadenitis (TBLA) as the final diagnosis were analysed among patients in whom EBUS-TBNA had been performed. All patients underwent routine clinical assessment and a CT scan prior to EBUS-TBNA. Demographic data, pathological findings, and microbiological results were recorded. All patients received 6-month antituberculous treatment, followed-up regularly and recovered both on clinical and radiological basis. Forty-four patients were included. EBUS-TBNA diagnosed TB intrathoracic lympadenopathy in 42 (95.4%) patients. In 2 patients, EBUS-TBNA was not able to confirm a diagnosis and additional procedures were required. Cytopathological findings alone revealed TB in 32 (72.7%) patients. One of the patients (2.2%) was smear positive while microbiological investigations provided a positive culture of TB in 22 (50%) patients. TB culture was positive in 10 ...Continue Reading
