Résumé
Pneumomediastinum, pneumothorax and subcutaneous emphysema are uncommon in pediatric practice, but they may be rarely ocured in association with respiratory distress and excessive ressusciation in the neonatal period, and as a complication of bronchial asthma, measles in childhood. And also, there was a report of a few cases that developed to pneumomediastinum and subcutaneous emphysema caused by vomiting in patient of diabetic coma. It is rare so far in this country that above events are complicated by miliary tuberculosis, but they may lead the patient to fatal and lifethreatening conditions, even though we perform a considerable medical treatment for that. We presnted 3 cases of 6 month 20 days old female infant, and each 10 year and 11 year old boys, developed to pneumomediastinu, pneumothorax and subcutaneous emphysema, and suddenly expired during hospital treatment of miliary tuberculosis. And, we reviewed the literatures, too.
