Correspondence: Dr. Snehal R Patel, Email: vibhav_5739@yahoo.in ABSTRACT Background: It is a very common experience of many physicians that a good number of extrapulmonary tuberculosis patients are suffering from asymptomatic pulmonary koch’s and many times it is diagnosed as a chance finding by chest X ray during routine investigation for general health check up or assessment for fit- ness purpose. Methodology: The present study was the cross-sectional study conducted on the randomly selected cases of extrapulmonary tuberculosis. A pre-designed semi-structured questionnaire was used to find out the presence of respiratory signs suggestive of symptomatic or asymptomatic pulmonary tuberculosis. In all participants, chest X ray, sputum for Acid Fast Bacilli (AFB), Complete Blood Count (CBC), ESR was done to find out or support pulmonary tuberculosis pathology. Results: Out of 140 patients of extrapulmonary tuberculosis 39.3% had pleural effusion, while almost similar number had abdominal Koch’s (37.9%) in the form of ileo-caecal Koch’s, mesenteric and para-aortic lymph nodes enlargement and tuberculous ascites. Pulmonary Koch’s was found out in 20 patients i.e. 14.3% of pa- tients. Conclusion: Profile of pulmonary pathology in extrapulmonary tuberculosis is not very high. We found only a small proportion (14.3%) of patients having associated pulmonary Koch’s that too was asymptomatic in majority (65%).Tuberculous pleural effusion and intestinal koch’s are the two commonest forms of extrapul- monary involvement. Key words: Extrapulmonary tuberculosis, pulmonary koch’s, Acid fast bacilli INTRODUCTION Tuberculosis can involve any organ system in the body. While pulmonary tuberculosis is the most common presentation, extrapulmonary tuberculosis (EPTB) is also an important clinical problem 1,2 . The term EPTB has been used to describe isolated occur- rence of of tuberculosis at body sites other than the lung. However, when an extrapulmonary focus is evident in a patient with pulmonary tuberculosis, such patients have been categorized under pulmo- nary tuberculosis as per the guidelines of the World Health Organization (WHO) 3 . Our study includes the effectiveness and necessity of sputum examination and pulmonary manifestations in patients of Extrapulmonary Tuberculosis. It is a very common experience of many physicians that a good number of extrapulmonary tuberculosis pa- tients are suffering from asymptomatic pulmonary koch’s and many times even pulmonary koch’s is diagnosed as a chance finding by chest X ray which has become routine investigation for general health check up or assessment for fitness purpose. The present study were based on the objective to find out the status of lung pathology i.e. symptomat-
