Role of USG in Thoracic Extrapulmonary Tuberculosis: Imaging Recommendations by the Society of Chest Imaging and Interventions

Abstract The expert group recommendations from the Society of Chest Imaging and Interventions extensively cover the role of ultrasound (USG) in diagnosing, guiding image-based sampling, and monitoring the follow-up of extrapulmonary tuberculosis (EPTB) in the thorax. The recommendations address the challenges of diagnosing EPTB due to its nonspecific symptoms and paucibacillary nature at various sites in the thorax (lymph nodes, pleura, pericardium, and chest wall). They emphasize USG as a readily available diagnostic tool. They underscore the importance of USG as a primary investigative method in managing EPTB, highlighting its utility based on the best available evidence and expert opinions.
