We studied the auscultatory findings in 117 patients with pulmonary tuberculosis and described findings using the new classification and terminology of lung sounds. The main auscultatory findings were bronchial breath sounds which were heard in 42 / 117 (35.9 %), and coarse crackles in 46 / 117 (39.1 %), respectively.
Auscultatory findings were also evaluated against chest X-ray. The infiltrative type (Type I) had fewer abnormal findings than the other 2 types. The sclerotic type (Type II), was characterized by bronchial breath sounds which were found in 29/57 (50.9%) and was often accompanied by coarse crackle which were found in 26/ 57 (45.6%). Severe or mixed type (Type III) presented auscultatory abnormalities and variegated sounds, i. e. bronchial breath sounds in 10/15 (66.7%) and coarse crackles in 12/15 (80.0 %).
Coarse crackles were auscultated in 50.0-55.6 % of patients expectorated sputa, but were not auscultated in patients with little sputa.
