Chest Radiographic Findings in Primary Pulmonary Tuberculosis: Observations from High School Outbreaks

The Institutional Review Board approved this retrospective study, with a waiver of informed consent from the patients. TB outbreaks occurred in 15 senior high schools and chest radiographs from 58 students with identical strains of TB were analyzed by restriction fragment length polymorphism analysis by two independent observers. Lesions of nodule(s), consolidation, or cavitation in the upper lung zones were classified as typical TB. Mediastinal lymph node enlargement; lesions of nodule(s), consolidation, or cavitation in lower lung zones; or pleural effusion were classified as atypical TB. Inter-observer agreement for the presence of each radiographic finding was examined by kappa statistics | Chest Radiographic Findings in Primary Pulmonary Tuberculosis Observations from High School Outbreaks Won-Jung Koh MD1 Yeon Joo Jeong MD2 O Jung Kwon MD1 Hee Jin Kim MD3 En Hi Cho MD4 Woo Jin Lew MD3 Kyung Soo Lee MD5 Index terms Adolescent Mycobacterium tuberculosis Pulmonary tuberculosis Thoracic radiography DOI 10.3348 kjr.2010.11.6.612 Korean J Radiol 2010 11 612-617 Received June 25 2010 accepted after revision July 1 2010.
