A 38-year-old male, with past history of pulmonary tuberculosis, was referred to us with worsening of dyspnea for 4 days. Dyspnea was initially relieved by bronchodilators, but for the past 2 days, there was no effect of the medications given. He denied any history of trauma, drug abuse, or vigorous exercise. His past history was significant for regular, adequate antituberculosis treatment taken 10 years back. Clinical examination revealed a hyperresonant percussion note, reduced intensity of breath sounds on left side, and presence of palpable crepitations over the neck and chest wall suggestive of surgical emphysema. The patient was in respiratory distress with tachypnea (34/min) and hypoxia (89%) on room air. An X-ray of the chest was done urgently [Figure 1].
