Background: The present study was conducted for evaluating occurrence of Spontaneous Pneumothorax (SP) secondary among TB patients. Materials &Methods: The present study was conducted for evaluating occurrence of SP secondary among TB patients. Data from clinical reports of every patient who received treatment for TB and secondary spontaneous pneumothorax (SSP) at the department of Chest and TB were analy sed. Age, sex, socioeconomic status, comorbi dity, past health history, clinical information, a diagnosis of active TB, and whether or not the patient was receiving anti-TB medication were all taken from the medical files. In all patients, SSP was diagnosed based on straightforward thoracic radiography. Bacteriological evidence has supported the TB diagnosis. All the results were recorded on a Microsoft excel sheet and were subjected to statistical analysis. Results: Pneumothorax was seen in 6 percent of the patients while hy dropneumot horax was seen in 4 percent of the patients. In all the patients, SSP was found to be unilateral. It was present on right side in 5 cases of pneumothorax while it was present in 3 cases of hydropneumothorax. On conventional radiography, out of 6 cases of pneumothorax, three patients had cavitary lesions and reticulonodular opacities. The average length of hospital stay was 31.5 days. Favourable clinical bacteriological and radiological outcomes were noted in only 4 cases of pneumothorax and 2 cases of hydropneumothorax. Conclusion: When a diagnosis is delayed, tuberculous pneumothorax is typically linked to active cavitated tuberculosis. With chest drainage and antitubercular treatment, the outcome was almost favourable.
